4e4ed5631f toolchain-external: apply kernel headers check to non-custom toolchains
Since the introduction of the kernel headers Config.in options, the
external toolchain logic had a check for custom external toolchains to
verify that the kernel headers version entered by the user matches the
one of the toolchain. However, this check was not made for non-custom
external toolchains (i.e the built-in profiles, such as Linaro,
CodeSourcery and al.), making the assumption that the Buildroot
developers will do the right selection.

However, it is quite nice when bumping external toolchains to have
this automatic kernel headers version check, to ensure we select the
appropriate kernel headers version.

Therefore, this commit makes the kernel headers version check
applicable to non-custom external toolchains.

77ef6a3a12 toolchain-external: restrict Musl external toolchain to Microblaze BE
As reported by William Welch <bvwelch@gmail.com>, the Musl external
toolchain provided by the musl-cross project is only Microblaze
big-endian. In fact, Musl seems to only support the big endian variant
of the Microblaze architecture, with the microblaze-* tuple.

This commit makes sure the Musl pre-built external toolchain provided
by musl-cross can only be selected for a big-endian Microblaze
configuration.

41486e1be8 toolchain-external: fix Linaro 2014.02 symlink
In commit cd32da8f79
("toolchain-external: add Linaro ARM big endian toolchain") a mistake
was made, probably due to a rebase conflict that was incorrectly solved:
the call to the post install staging hook that creates the necessary
symbolic links for a root filesystem based on Linaro 2014.02 to work
was removed.

This commit reinstates this call, which should fix the problem
observed by Maxime Hadjinlian while using Linaro 2014.02.

7130ceb267 toolchain: generate a gdbinit file
This commit slightly improves the external toolchain backend, and the
gdb build logic to create a file named
$(STAGING_DIR)/usr/share/buildroot/gdbinit which can be used as a
gdbinit file using gdb -x option. This allows gdb to automatically use
the proper sysroot to find libraries.

The initial insight for this patch comes from the report of Oded
Hanson <OHanson@xsightsys.com>, who found an issue with the Eclipse
Buildroot plugin, which was setting a solib-path in gdb, but not a
sysroot. Setting a solib-path was enough to find shared libraries, but
not the dynamic linker. And since Eclipse doesn't allow to set the
sysroot in any other way than giving a gdbinit file, it makes sense to
have Buildroot generate a gdbinit file (which can be used in other
situations than Eclipse).

To achieve this, this commit introduces a gen_gdbinit_file helper in
toolchain/helpers.mk, and uses it for the internal toolchain and
external toolchain backends.

e48ef3f522 toolchain-external: Introduce kernel headers sanitization
The Nios-II Sourcery external toolchain (the only Nios-II we currently
support) exports broken kernel headers. In particular, these kernels should
be exported using the "headers_install" rule which applies a set of fixes
on the kernel headers so they are suitable for userspace usage.

In order to fix this, add a post-install hook to perform the header fixes
ourselves. The result is equivalent to apply the "headers_install" rule.

2a82bb8a90 support/check-kernel-headers: fix old custom toolchains without -print-sysroot
Old toolchains, with old gcc that do not support -print-sysroot, break the
kernel-headers version check script: it fails to find the sysroot of the
toolchain, and thus ends up including the host's linux/version.h.

Most of the time, this will break early, since the host's kernel headers
will not match the toolchain settings.

But it can happen that the check is succesful, although the configuration
of the toolchain is wrong:

  - the custom toolchain has kernel headers vX.Y
  - the user selected vX.Z  (Z!=Y)
  - the host has headers vX.Y

In this case, the check passes OK, but the build of some packages later on
will break (which is exactly what those _AT_LEAST_XXX options were added to
avoid).

Fix that by passing the sysroot to the check script, instead of the cross
compiler.

We get the sysroot as thus:

  - for custom toolchains, we use the macro toolchain_find_sysroot. We can
    do that, because we already have a complete sysroot with libc.a at that
    time.

  - for internal toolchain using a custom kernel headers version, we just
    use $(STAGING_DIR). We can't use the macro as for custom toolchains
    above, because at the time we install the kernel headers, we do not yet
    have a complete sysroot with a libc.a.  But we can just use
    $(STAGING_DIR), since we're only interested in the kernel headers.

For all other types of toolchains, we already have the _AT_LEAST_XXX options
properly set, so we need not add a check in this case.

a1a86ebfba liburcu: disable build with gcc-4.8.x on ARM
Because of a gcc bug [1], liburcu checks for compiler version [2] and
stops the build prematurely if gcc-4.8.[0-2] is detected for ARM.

However a bug fix exists [3] and may be backported by ARM toolchain
providers; that's what is done in Buildroot [4] or Linaro [5].

So, this change:
- add a patch in liburcu to allow build with ARM gcc-4.8.2;
- adds a new hidden symbol to reflect the toolchain status with regard
  to this bug [1];
- and controls liburcu visibility.

However, a limitation of this is when the user is using a custom
toolchain; that's why the bug details have been added in the liburcu
help message.

a5a309642a toolchain/external: check kernel headers version for custom toolchain
Ensure the kernel headers version used in the custom external toolchain,
or the manually-specified kernel headers version, matches exactly the one
selected by the user.

We do not care about the patch-level, since headers are not supposed to
change between patchlevels. This applies only to kernels >= 3.0, but
those are actually the ones we do care about; we treat all 2.6.x kernels
as being a single version, since we do not support any 2.6 kernels for
packages with kernel-dependant features.

c64f948d2c toolchain: introduce a toolchain knob for NPTL
As our architecture support expands to a number of architectures that
do not implement NPTL threading, and the number of packages that
depend on NPTL specific features, it has become necessary to be able
to know whether the toolchain has NPTL support or not.

This commit adds a new BR2_TOOLCHAIN_HAS_THREADS_NPTL hidden Config.in
option that allows packages to know whether NPTL is available or not.

This hidden option is:

 * Automatically enabled when glibc/eglibc or musl toolchains are
   used, either internal or external.

 * Automatically enabled when an internal uClibc toolchain with NPTL
   support is configured. It is left disabled otherwise for internal
   uClibc toolchains.

 * Configured according to a visible Config.in option for custom
   external uClibc toolchains.

This commit makes the dependency from the target toolchain explicit.
This way we can buid from command line a package that use
inner-generic-package right after the configuration phase, example:

	make clean <package-name>

Also remove TARGETS_ALL because the only purpose was to add toolchain
dependency so it's superseded by this commit.

To prevent circular dependency add the new variable
<pkgname>_ADD_TOOLCHAIN_DEPENDENCY to avoid adding the toolchain
dependency for toolchain packages.

This is also a step forward supporting top-level parallel make.

ba4ad9d27c deprecated handling: introduce BR2_DEPRECATED_SINCE_xxxx_xx
In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.

A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

2c1dc32647 toolchain/external: fix wrapper by not passing conflicting flags
In our wrapper, we forcibly add the -march=, -mcpu= and-mtune= flags
to the actual compiler, this in an attempt to always generate correct
and optimised code for the target.

But in some cases, the caller knows better than we do, and passes its
own set, or subset of those flags. In this case, some may conflict with
the ones we pass. The most prominent offender being the Linux kernel.

For example, on the ARM Raspberry Pi, the Linux kernel will set the
-march=armv6 flag and no -mcpu= flag, but we pass -mcpu=arm1176jzf-s,
which conflicts:

    drivers/scsi/scsi_trace.c:1:0: warning: switch -mcpu=arm1176jzf-s
    conflicts with -march=armv6 switch

(and so for all the files the kernel compiles, pretty messy)
(note: arm1176jzf-s is not an armv6, it is an armv6zk. Yeah...)

To avoid this situation, we scan our commandline for any occurence of
the possibly conflicting flags. If none is found, then we add our owns.
If any is found, then we don't add any of our owns.

The idea behind this is that we trust the caller to know better than
we do what it is doing. Since the biggest, and sole so far, offender
is the Linux kernel, then this is a rather safe bet.

removes the support for the Sourcery MIPS 2012.03 toolchain.

While we're at it, also fix the incorrect help text related to the
MIPS64 multilib selection.

620d85b310 toolchain-external: fix the SYSROOT_DIR mangling logic
In a1d94aaa3a ('toolchain-external: add support for musl C
library'), we made the following change to the SYSROOT_DIR mangling
logic:

-       SYSROOT_DIR=`echo $${LIBC_A_LOCATION} | sed -r -e 's:usr/lib(32|64)?/(.*/)?libc\.a::'` ; \
+       SYSROOT_DIR=`echo $${LIBC_A_LOCATION} | sed -r -e 's:(usr/)?lib(32|64)?/(.*/)?libc\.a::'` ; \

This was needed to accomodate for musl based toolchains that don't
have libc.a in usr/lib/..., but directory in lib/... Basically, the
change makes the usr/ at the beginning optional.

However, with the very permissive (.*) matching in the middle of the
path, the change above had an unexpected consequence: any path contain
'/lib' would be truncated before this lib. As an example, Peter
reported that his builds, running from /var/lib/buildbot/ were no
longer working because the SYSROOT_DIR was decided to be /var instead
of something like
/var/lib/buildbot/buildroot/output/host/opt/ext-toolchain/arm-linux-gnueabihf/libc/.

So, this commit changes (again!) this regexp by changing (.*) to
([^/]*), the idea being that it will match only *one* path
component. Note that this intermediate (.*) directory was added in
e6e60becb0 ('external-toolchain: add support for Linaro 2012.01') to
accomodate for Linaro toolchains that have a subdirectory in their
sysroot named after the target tuple:

$ ./output/host/opt/ext-toolchain/bin/arm-linux-gnueabihf-gcc -print-file-name=libc.a
/home/thomas/projets/buildroot/output/host/opt/ext-toolchain/bin/../arm-linux-gnueabihf/libc/usr/lib/arm-linux-gnueabihf/libc.a

In addition to this, this commit also makes sure that the change
making usr/ optional is properly reported on all the instances of this
regular expression.

relying on the BR2_PACKAGE_GDB option, which is enabled when native

1e0b97d166 toolchain-external: fix visibility and length of Linaro toolchain comment
Maxime Ripard reported that the Linaro toolchains were not visible
when selecting a Cortex-A, but forgetting to set the EABI to
EABIhf. While this is expected, Buildroot should normally should a
comment in this case. However, the comment is only visible when the
selected ARM architecture is not ARMv7 *and* the EABI is not
EABIhf. Instead, make the comment visible when either the selected
architecture is not ARMv7 *or* when the selected EABI is not EABIhf.

While we're at it, reword the comment text so that it actually fits
within the limits of the menuconfig screen.

b3e3d5fc28 toolchain-external: add missing symlink for Linaro toolchains
In 11ec38b695 ("toolchain-external: fix Linaro ARM toolchain
support"), we fixed the support for Linaro EABIhf toolchains by adding
a /lib/arm-linux-gnueabihf -> /lib symbolic link. This is needed
because the dynamic loader looks for libraries in
/lib/arm-linux-gnueabihf rather than the usual /lib, but Buildroot
installs all libraries in /lib.

However, we forgot that the dynamic loader also loads libraries from
/usr/lib/arm-linux-gnueabihf rather than /usr/lib, so this patch fixes
that by adding the necessary symbolic link.

We fix this by appending "-EL" to the toolchain wrapper options

1247850d44 toolchain-external: add a specific check to avoid Angstrom toolchains
The Angstrom toolchains available at
http://www.angstrom-distribution.org/toolchains/ are not usable as
external toolchains in Buildroot, because they are not pure toolchains
with just the C library, but instead complete SDKs with many
cross-compiled libraries (Gtk, Qt, glib, neon, sqlite, X.org, and many
more, approximately 200 MB of libraries).

Buildroot cannot use such toolchains, and while this is documented in
our manual, some users still try to do this. Today, one such user came
on the IRC channel, reporting a build problem, which we started
investigating, only to realize after a long time that he was using an
Angstrom toolchain.

To avoid this problem in the future, we explicitly check if the
toolchain is from Angstrom by looking at the vendor part of the tuple
exposed by the toolchain: as soon as it is
<something>-angstrom-<something-else>, we reject the toolchain with an
explanation.

11ec38b695 toolchain-external: fix Linaro ARM toolchain support
This commit fixes bug #6452 (eglibc from Linaro 2013.07 not copied to
target correctly) by:

 * Copying only the relevant library loader to the target on ARMhf
   (i.e ld-linux-armhf.so and not ld.so*). This is needed since Linaro
   toolchains provide two library loaders, one ARMv7 hf, and one ARMv4
   soft-float.

 * Making sure a $(TARGET_DIR)/lib/arm-linux-gnueabihf/ symbolic link
   to $(TARGET_DIR)/lib/ exists, since the dynamic loader of Linaro
   toolchains expects libraries to be found in
   $(TARGET_DIR)/lib/arm-linux-gnueabihf/.

a1d94aaa3a toolchain-external: add support for musl C library
This commit adds support for external toolchains based on the musl C
library, as available from http://www.musl-libc.org.

Note that the pre-built musl toolchains available from
http://musl.codu.org/ are not working for the moment, since they lack
sysroot support. However, this problem has been reported to the
maintainer, who has already added sysroot support in his scripts at
https://bitbucket.org/GregorR/musl-cross, and therefore the next
version of the pre-built toolchains should work with Buildroot
out-of-the-box. In the mean time, the musl-cross script must be used
to build the toolchain.

186a99b1c6 toolchain: modify the wildcard logic for shared libraries copying
Until now, the copy_toolchain_lib_root function took as argument the
base name of a library (e.g: libm.so), and was assuming that the usual
scheme libm.so.<x> being a symbolic link to the real library was used.

However, with musl based toolchains, the C library is named libc.so
directly, with no symbolic link at all. Therefore, this commit changes
the copy_toolchain_lib_root to move the responsibility of using a
wildcard or not after the library name the caller's responsibility.

So, all the existing LIB_EXTERNAL_LIBS values are modified to have a
.* at the end, so that the behavior is effectively unchanged.

36ef1b4494 toolchain-external: conditionalize the installation of libraries
The external toolchain code makes the assumption that all C libraries
have a ld*.so, libc.so, libcrypt.so, libdl.so, libgcc_s.so, libm.so,
libnsl.so, libresolv.so, libutil.so, and when thread support is
enabled, libpthread.so, etc.

However, this is not the case with the musl C library, which
integrates all the functionalities in a single libc.so file. In
preparation of the support of the musl library, we make the current
value of LIB_EXTERNAL_LIBS conditional to glibc or uClibc.

The addition of additional libraries through
BR2_TOOLCHAIN_EXTRA_EXTERNAL_LIBS is kept outside the condition, at
the end.

d07d2bfeb2 toolchain-external: convert to the package infrastructure
This commit converts the 'toolchain-external' logic to the package
infrastructure.

The TOOLCHAIN_EXTERNAL_DIR variable (which points to where the
toolchain is located) is renamed to TOOLCHAIN_EXTERNAL_INSTALL_DIR,
because the former conflicts with the package infrastructure (which
defines the <pkg>_DIR variable for each package as pointing to its
build directory).

The new _EXTRA_DOWNLOADS mechanism is used for Blackfin toolchains.

The extract, configuration and installation steps are converted inside
the <pkg>_EXTRACT_CMDS, <pkg>_CONFIGURE_CMDS and
<pkg>_INSTALL_STAGING_CMDS.

60cb290475 toolchain/wrapper: add option to print one argument per line
In case there are many arguments passed to the tools, the command line
can get very long, and difficult to parse visually.

For example, the Linux kernel passes a lot of arguments to gcc (at least
45, which gives 53 with our hard-coded args). Looking at such a command
line is daunting.

So, add the possibility to print each argument on its own line.

Also, enclose all args between single quotes, so the command line
can be safely copy-pasted without special chars (spaces, $) being
inrerpreted by the shell.

Add blurb about toolchain-wrapper to documentation at the same
time.

c5866be0ad toolchain: refactor Stack Smashing Protection support
This commit refactors how Stack Smashing Protection support is handled
in Buildroot:

 *) It turns the BR2_TOOLCHAIN_BUILDROOT_USE_SSP option into an option
    that only enables the SSP support in uClibc, when using the internal
    toolchain backend.

 *) It adds an hidden BR2_TOOLCHAIN_HAS_SSP option that gets enabled
    when the toolchain has SSP support. Here we have the usual dance:
    glibc/eglibc in internal/external backend always select this
    option, in the case of uClibc/internal, it gets selected when
    BR2_TOOLCHAIN_BUILDROOT_USE_SSP is enabled, in the case of
    uClibc/external, there is a new configuration option that the user
    must select (or not) depending on whether the toolchain has SSP
    support.

 *) It adds a new options BR2_ENABLE_SSP in the "Build options" menu,
    to enable the usage of SSP support, by adding
    -fstack-protector-all to the CFLAGS.

97565866e8 toolchain-external: don't create gdb symlink when building host-gdb
The external-toolchain infrastructure creates symbolic links for all
tools in the host directory. However, when buildroot builds its own
version of a cross debugger (BR2_PACKAGE_HOST_GDB), and the toolchain
also provides a cross debugger, there would be two symbolic links for
gdb in the host directory, which is confusing.
An example use case is where the external toolchain only provides a
64-bit gdbserver (e.g. Cavium Networks SDK) but the target is completely
32-bit (e.g. n32 ABI). In this case, using gdbserver on target requires
copying a bunch of 64-bit libraries to the target as well, just for gdb.
In this case, one can let buildroot build both gdbserver as cross-gdb
(both in 32-bit).

This patch modifies the symlink creation so that no gdb (or gdbtui)
symlink is created if buildroot is going to build a cross-gdb.

b2e88073db toolchain: check ARM EABI vs. EABIhf for external toolchains
Following the introduction of the support of EABIhf as a second ARM
ABI, it is important to check whether the external toolchain provided
by the user actually uses the ABI that has been selected in the
Buildroot configuration. This commit introduces such a check by
looking at the 'Tag_ABI_VFP_args' tag of the architecture-specific
section of the ELF headers. This assumes that ELF is the binary format
used on ARM, which may not be the case on ARM noMMU systems (they use
the FLAT binary format), but Buildroot doesn't have support for such
systems at the moment.

Also ensure the correct CFLAGS are passed to the cross compiler for the
test, so the correct variant is used in case the toolchain is multilib.

85d0769ac5 arch/arm: add support for Thumb2
Until now, we were using the default ARM instruction set, as used by
the toolchain: the 32 bits ARM instruction set for the internal
backend, and for external toolchain, whatever default was chosen when
the toolchain was generated.

This commit adds support for the Thumb2 instruction set. To do so, it:

 * provides a menuconfig choice between ARM and Thumb2. The choice is
   only shown when Thumb2 is supported, i.e on ARMv7-A CPUs.

 * passes the --with-mode={arm,thumb} option when building gcc in the
   internal backend. This tells the compiler which type of
   instructions it should generate.

 * passes the m{arm,thumb} option in the external toolchain
   wrapper. ARM and Thumb2 code can freely be mixed together, so the
   fact that the C library has been built either ARM or Thumb2 and
   that the rest of the code is built Thumb2 or ARM is not a problem.

ea6b277539 toolchain-external: update config options after EABIhf introduction
The introduction of the EABIhf ABI requires a few updates to the
configuration options for external toolchains, in order to ensure that
the user doesn't do any invalid selection. In detail:

 * The Linaro ARM toolchains now depend on BR2_ARM_EABIHF, because
   that's the ABI they use, and it is incompatible with EABI. The
   comment about the availability of Linaro toolchains is updated to
   inform users selecting EABI that they should select EABIhf if they
   want to see Linaro toolchains.

 * The Sourcery CodeBench toolchains now depend on BR2_ARM_EABI,
   because that's the ABI they use. A comment is added to inform users
   that have selected EABIhf that Sourcery CodeBench are only
   available when EABI is used.

 * The Arago toolchains now depend on BR2_ARM_EABI, because that's the
   ABI they use. The description of the ARMv7 Arago toolchain is also
   slightly improved.

381616e77a Introduce BR2_TOOLCHAIN_USES_{UCLIBC, GLIBC}
Currently, when we need to do a conditional on the type of C library
used, we need to take into account the three toolchain backends. As we
are going to add eglibc support to the Buildroot toolchain backend, it
would become even uglier, so this patch introduces two new hidden
options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that
exist regardless of the toolchain backend. The entire Buildroot code
base is converted to use those options.

Note that we have intentionally created only one option
(BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are
essentially the same, as far as Buildroot is concerned.

8b4ade86aa toolchain-external: Install blackfin FDPIC and FLAT libraries
For certain situations, users may want to install shared FLAT
libraries to the target filesystem even if FDPIC is used as the
primary binary format, or symmetrically users may want to install FDPIC
libraries to the target filesystem even if shared FLAT is used as the
primary binary format.

This commit allows that by:

 * Offering additional Kconfig options to install shared FLAT or FDPIC
   libraries even when those libraries are not selected as the primary
   binary format.

 * Preserving all Blackfin toolchain folders under the
   TOOLCHAIN_EXTERNAL_DIR, instead of keeping only the one related to
   the selected binary format.

 * Adding some additional install targets that do the installation of
   either the shared FLAT or FDPIC libraries when requested.

603293f5ff toolchain-external: fix bug #5054
The external toolchain logic checks (and finds) the proper ARCH_LIB_DIR
and forcibly copies it to */lib even if it's in */lib64
This is all well until the check is done for create_lib64_symlinks which
only verifies if ARCH_SYSROOT_DIR/lib64 is a symlink, which in some
toolchain it's a real directory (like sourcery x86_64 2012.09) and thus
doesn't make the symlink in the target.

Fix this by also checking for a real directory.

Easily reproducible by running "make qemu_x86_64_defconfig", switching
to an external toolchain before build, building and then trying to run
the resulting image.

a0b6faaab4 gdb: convert to the package infrastructure
This commit converts gdb to the package infrastructure, and therefore
moves it from toolchain/gdb to package/gdb.

The target package is now visible in "Package selection for the
target" => "Debugging, profiling and benchmark". The main option,
"gdb", forcefully selects the "gdbserver" sub-option by
default. Another sub-option, "full debugger" allows to install the
complete gdb on the target. When this option is enabled, then
"gdbserver" is no longer forcefully selected. This ensures that at
least gdbserver or the full debugger gets built/installed, so that the
package is not a no-op.

The host debugger is still enabled through a configuration option in
"Toolchain". It is now visible regardless of the toolchain type (it
used to be hidden for External Toolchains). The configuration options
relative to the host debugger are now in package/gdb/Config.in.host,
similar to how we have package/binutils/Config.in.host.

Since gdb is now a proper package, it is no longer allowed to 'select
BR2_PTHREADS_DEBUG' to ensure thread debugging is available when
needed. Instead, it now 'depends on
BR2_TOOLCHAIN_HAS_THREADS_DEBUG'. This option, in turn, is selected by
the different toolchain backends when appropriate. The
'BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED' option is removed, since
we no longer need to know when it is allowed to 'select
BR2_PTHREADS_DEBUG'. Also, the 'BR2_PTHREADS_DEBUG' option is moved to
appear right below the thread implementation selection (in the case of
the Buildroot toolchain backend).

313094d787 toolchain-external: add new Microblaze toolchains
The existing Microblaze toolchains that we have have the annoying
property of being based on a very old glibc version: 2.3.6. Xilinx
provides newer toolchains with glibc 2.14, generated by Crosstool-NG,
but they are only available as part of a huge Git repository that
contains the gcc, Linux, binutils, glibc sources unpacked (4.4 GB
total), which makes is very unpractical.

I contacted the Xilinx person who did those toolchains, but they
apparently didn't intend to change that anytime soon.

So, we have created a tarball for those toolchains, adding a
README.txt file in the tarball that points back to the original
location that contains the source code for them. Those tarballs are
hosted on sources.buildroot.net.

This commit then adds support for those two new external toolchains,
one for little endian Microblaze, another one for big endian
Microblaze.

befb9a3ee0 Make external toolchain relocatable
The external toolchain wrapper sets sysroot etc. to an absolute path.
By changing this to a relative path, it is possible to move the host
directory to a different location and still have a working build
system.

This only works for a downloaded external toolchain.  For a pre-installed
external toolchain, it is possible to move the host directory to a
different location, but not the external toolchain directory (it does work
if the external toolchain directory lies within the host directory).  For
an internal or crosstool-ng toolchain, there is no wrapper so updating the
sysroot path should be done in a different way.

See http://lists.busybox.net/pipermail/buildroot/2012-February/050371.html
for information about others things to do to make the host directory
relocatable.

9fbdf062b9 toolchain-external: improve glibc support to test availability of RPC
Basically, the BR2_TOOLCHAIN_EXTERNAL_GLIBC option no longer
unconditionally selects BR2_TOOLCHAIN_HAS_NATIVE_RPC since there are
glibc toolchains that don't have RPC support. All the predefined
toolchain profiles are updated to take into account this change: for
the moment, all glibc toolchains that have pre-defined toolchains have
RPC support, but further patches in the series add pre-defined glibc
toolchains that don't have RPC support. In the case of custom glibc
toolchains, a question is asked to the user so that he can say whether
the external glibc toolchain has RPC support or not. The validity of
this configuration option is checked by the new
check_glibc_rpc_feature function in helpers.mk.

df0c125994 toolchain-external: allow downloading a custom toolchain
This patch adds the possibility to download a custom external
toolchain, in addition to the existing support of preinstalled custom
external toolchains.

With the modified configuration, the user is presented with the
following options:
- Toolchain type: Buildroot toolchain | External toolchain | Ct-ng toolchain

In case of External toolchain:
- Toolchain: the CodeSourcery toolchains | Custom toolchain
- Toolchain origin: Toolchain to be downloaded and installed | Pre-installed toolchain

In case of Toolchain to be downloaded, the user is presented with:
- Toolchain URL
In case of Pre-installed toolchain, the users sees:
- Toolchain Path

For CodeSourcery toolchains, the toolchain URL field is not used (the
URLs are directly coded in ext-tool.mk).

d8e1ecb855 ext-tool.mk: fix SUPPORT_LIB_DIR calculation for toolchains without libstdc++
SUPPORT_LIB_DIR would get resolved to the main buildroot directory for
external toolchains without C++ support, as:

 - gcc -print-file-name=<nonexisting-file> returns <nonexisting-file>
 - readlink -f <nonexisting-file> returns $PWD/<nonexisting-file>

So fix it by ensuring output of gcc -print-file-name actually exists
before using it.

e1f0804cc1 external-toolchain: add support for recent Linaro toolchains
Starting from 2012.03, the Linaro toolchains have separated the GCC
support libraries (libstdc++, libgcc_s) from the sysroot itself. So we
no longer have the case where all libraries are inside the sysroot, as
we had for all the previously supported toolchains.

Therefore, we add some logic to detect if such a separate directory is
used for GCC support libraries, and if it's the case, we make sure
that we take into account this directory when creating our own
sysroot, and when copying libraries to the target filesystem.

0a4856ce27 DOWNLOAD: change $1=DIRECTORY_URL, $2=FILE_NAME to $1=FULL_FILE_URL, $2=FILE_NAME
This modifies the definition of DOWNLOAD to receive two arguments:
the first one is the full URL of the file to download, whereas the second
(and optional) is the name the file will have once downloaded.

Same thing with the SOURCE_CHECK_WGET and SCP functions.

All calls to these functions have been changed to the shortest form of
the new API, except for toolchains acquisition. Since there is quite a
number of different toolchains this call to DOWNLOAD is better set to the
generic one.

c56b58b4b7 debug: provide an option to copy the gdbserver to the target
When an external toolchain is used, it is very likely that it contains
a pre-built version of a gdbserver that has the same version as the
cross-gdb included in the external toolchain. So, we now provide an
option that allows to copy this pre-built gdbserver to the target.

As the location of the gdbserver in the external toolchain is not
standardized, we only support the CodeSourcery and Crosstool-NG
layouts for the moment. Other locations can be added later.

e6e60becb0 external-toolchain: add support for Linaro 2012.01
Linaro has just released a new pre-built toolchain, available as a
tarball, which is a pure toolchain (only the C library is
included). This makes this new Linaro 2012.01 toolchain usable in
Buildroot, so let's integrate the support for it.

In addition to simply adding the new external toolchain at the usual
locations, this patch allows need to adapt a few things to support
Linaro toolchains. Most toolchains store their libraries in the "lib/"
or "usr/lib" directories relative to the toolchain. Buildroot
toolchains on the other hand, store the libraries in the
"usr/<target-name>/lib" directory. And the Linaro toolchain has
choosen to use the "lib/<target-name>" directory. Therefore, this
patch adjust:

 * The logic to search a particular library when that library needs to
   be copied to the target directory

 * The logic to deduce the sysroot directory from the libc.a file
   location in the toolchain: removing "(usr/?)lib(64?)" is no longer
   sufficient, we need to take into account the "lib/<target-name>/"
   case.

Since the Linaro toolchain generates code for Cortex-A processors
only, the selection of this toolchain is limited to Cortex-A8 and
Cortex-A9.

0729b544b3 Improve external toolchain logic to support IA32 Sourcery CodeBench toolchain
The IA32 Sourcery CodeBench toolchain has a relatively special
structure, with the following multilib variants:

 * Intel Pentium 4, 32 bits, the multilib variant is in ./ relative to
   the main sysroot, with the libraries in the lib/ directory.

 * Intel Xeon Nocona, 64 bits, the multilib variant is in ./ relative
   to the main sysroot, with the libraries in the lib64/ directory.

 * Intel Atom 32 bits, the multilib variant is in atom/ relative to
   the main sysroot, with the libraries in the lib/ directory.

 * Intel Core 2 64 bits, the multilib variant is in core2/ relative to
   the main sysroot, with the libraries in lib64/ directory.

So the first two variants are in the same sysroot, only the name of
the directory for the libraries is different.

Therefore, we introduce a new ARCH_LIB_DIR variable, which contains
either 'lib' or 'lib64'. This variable is defined according to the
location of the libc.a file for the selected multilib variant, and is
then used when copying the libraries to the target and to the staging
directory.

In addition to this, we no longer use the -print-multi-directory to
get the ARCH_SUBDIR, since in the case of the 64 bits variants of this
toolchain, it returns just '64' and not a real path. Instead, we
simply compute the difference between the arch-specific sysroot and
the main sysroot.

We also take that opportunity to expand the documentation on the
meaning of the different variables.

5931db0de9 gdb: fix kconfig dependency handling with !BR_TOOLCHAIN_BUILDROOT
Newer versions of GDB need pthread debugging support if threads are
enabled, which is always the case for glibc but is a configure option
for uClibc.

We have solved this for internal toolchains by selecting the
BR2_PTHREAD_DEBUG option from the GDB selection if needed, but as this
option isn't available when ctng/external toolchains are used, mconf
prints ugly warnings and the build may fail if an external uClibc
toolchain without pthread debugging support is used.

Fix it by introducing 2 more hidden config options:
 - BR2_TOOLCHAIN_HAS_THREADS_DEBUG
 - BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED

The first tells us if the toolchain HAS pthreads debugging support,
and is checked by check_uclibc_feature in helper.mk for external uClibc
based toolchains.

The second tells us if the toolchain is ABLE TO provide pthreads debugging
support if threads are enabled, either because it's an internal toolchain
where we can force enable it or an external glibc/eglibc toolchain or
uClibc with the option enabled.

Crosstool-ng forcibly enables this support, so those will always work.
The preconfigured uClibc-based toolchains we have also all enable it.

Finally, show a comment if this isn't the case so the (external toolchain)
user knows why. This is placed outside the choice option, as menuconfig
has a bug where it doesn't show choice selections which only contain
comments.
