Don't enable SSP support on external toolchains just because they use
glibc or musl. Instead of that, make the external toolchains explictily
declare if they support SSP or not. And also add a check to detect SSP
support when using custom external toolchains.
For internal toolchains we always enable SSP support for glibc and musl.

So user provided libraries defined in BR2_TOOLCHAIN_EXTRA_EXTERNAL_LIBS
are not copied anymore to staging and target directories.

The toolchain-external logic is roughly:
- populate the staging dir by rsyncing the entire ${ARCH_LIB_DIR} and
usr/${ARCH_LIB_DIR} from sysroot.
- populate the target dir by explictly copying some libraries from sysroot
into target/lib and some other libraries in target/usr/lib, the split
being hardcoded into buildroot regardless of the location in the sysroot.
This means that a library libfoo could be located in:
staging/lib/libfoo.so
target/usr/lib/libfoo.so
When debugging an application that links against this library, gdb will
fruitlessly search for 'usr/lib/libfoo.so' in staging, and then suggest to
use 'set solib-search-path' which is a hack, really.
To solve the problem, we need to make sure that libraries from the toolchain
are installed in the same relative location in staging and target.
Achieve this by:
- replacing the convoluted search for libraries using for+find in sysroot
with a simple find in staging.
- determining DESTDIR for each library individually based on the location in
staging.
- treating LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS equivalently
These changes also allow for the removal of most arguments to
copy_toolchain_lib_root in the method itself and their callers.
Test procedure:
- set configuration for a given toolchain
- make clean toolchain
- find output/target | sort > /tmp/out-before
- apply patch
- make clean toolchain
- find output/target | sort > /tmp/out-after
- diff -u /tmp/out-before /tmp/out-after
The only changes should be some libraries moving from lib to usr/lib or vice
versa. Notable examples being libstdc++ and libatomic.

When a toolchain is glibc based, the getent package assumes that
$(STAGING_DIR)/usr/bin contains the getent program. Unfortunately, the
Codescape MIPS toolchains do not conform with this:
$(STAGING_DIR)/usr/{bin,sbin} are empty, and instead three directories
are provided: bin-o32, bin-n32 and bin-n64 (ditto for sbin), one for
each supported MIPS ABI.
Since this is a toolchain-specific oddity, we handle it by adding a
post-install fixup hook that creates $(STAGING_DIR)/usr/{bin,sbin} as
symbolic link to the appropriate directory.

As we currently download the actual sources as part of saving the
legal-info, we do not check the hashes of those downloads.
That's because, during legal-info, there is not package involved, and
thus there's no path to an actual .hash file.
However, this precludes legal-info from working in off-line mode. A
subsequent patch will make it possible to do so, and actual sources will
be downloaded as another classical package download.
This will have two consequences:
- first, we will be able to add hashes for actual sources, so we can
ensure their integrity,
- second, and as a direct consequence of the above, when a .hash file
is present, it would have to list all the hashes for that package,
or that would be treated as an error.
Currently, the only package that falls in this case is the external-
toolchain, for which we have means to retrieve the sources for some of
the toolchains.
So we just add hashes for those actual external-toolchain sources we may
have to download.
Those hashes are not used for now, but they'll come into play a few
patches down.

While the prebuilt musl toolchains provided by http://musl.codu.org/
had not been updated in a while, a new release based on musl 1.1.12
has been put online in December 2015. This commit updates our external
toolchain package to use this new pre-built toolchain.
Compared to the previous 1.1.6 toolchain, there are some changes:
- The MIPS big endian soft-float variant is no longer available.
- The Microblaze variant is no longer available.
- SuperH 4, both little and big endian, variants have been added.
- The components have been updated: gcc 5.3 is used, binutils 2.25.1,
and of course musl 1.1.12.
Besides the update itself, in this commit, we are:
- Making the musl toolchain non-selectable on MIPS big endian
soft-float.
- Making the musl toolchain actually work on MIPS little endian
soft-float, by downloading the right tarball and setting up the
right symbolic link.
- Removing support for the Microblaze variant, and adding support for
the SH4 variants.
All variants except armeb have been boot tested under Qemu, up to a
Busybox shell prompt. armeb has not been tested due to the lack of a
Qemu configuration for this architecture.

Currently, following symbolic links are created in both target and
staging directories:
- lib(32|64) --> lib
- usr/lib(32|64) --> lib
The decision for lib32 or lib64 is based on the target architecture
configuration in buildroot (BR2_ARCH_IS_64).
In at least one case this is not correct: when building for a Cavium Octeon
III processor using the toolchain from the Cavium Networks SDK, and
specifying -march=octeon3 in BR2_TARGET_OPTIMIZATION, libraries are expected
in directory 'lib32-fp' rather than 'lib32' (ABI=n32; likewise for
lib64-fp in case of ABI=n64)
More generally the correct symbolic link is from (usr/)${ARCH_LIB_DIR}->lib.
However, feedback from Arnout Vandecappelle is that there are packages that
do depend on the lib32/lib64 symlink, even if ARCH_LIB_DIR is different.
Hence, these links must be kept.
Fix the problem as follows:
- For internal toolchains: no change
- For external toolchains: create a symlink ARCH_LIB_DIR->lib if
(usr/)ARCH_LIB_DIR does not exist yet.

As reported by Yann E. MORIN [1], the latest CS PowerPC toolchain (2012.03)
requires a PPC CPU with SPE, which is basically two variants, 8540 (e500v1) and
8548 (e500v2) in Buildroot. All other PPC CPU can't use that toolchain.
Keep CS PowerPC 2011.03 as latest available version and add a second Kconfig
symbol for the CS PowerPC 2012.03 since it's verry specific to one CPU type
(e500v2).
Previously it was possible to select the CS 2012.03 with a powerpc 8540 (e500v1)
CPU but the sysroot provided by the toolchain only support the 8548 (e500v2)
variant. Allow to select CS 2012.03 only with BR2_powerpc_8548.
Also re-add the previous CS toolchain handling for pixman and liquid-dsp.

Musl does not provide a 'sys/queue.h' implementation, and this has been
a problem for packages that depend on it.
So lets create a package called netbsd-queue that will install a
'sys/queue.h' in the staging directory when enabled, based on the
NetBSD implementation.
Musl toolchain and external toolchain packages will depend on this
package, so that 'sys/queue.h' will be always installed when compiling
with a musl based toolchain.
Tested on ARM and x86 in the following cases:
- Buildroot musl toolchain.
- External musl toolchain without 'sys/queue.h'.
- External musl toolchain with 'sys/queue.h'.

Commit 23ffa7ec first extracts to the toolchain-external build
directory and then moves everything to $(HOST_DIR)/opt/ext-toolchain.
However, this is not idempotent, because moving directories over

Simply remove the destination contents before moving.

Now that packages can provide a list of files to be excluded when
extracting their archive, downloaded external toolchains are no longer
special in this respect.
Still, those toolchains are currently extracted directly into their
final location, $(HOST_DIR)/opt/ext-toolchain/ which means we still
need a custom extract command.
Except, we don't really need it: we can just move the toolchain, after
it's been extracted by the generic extract command, with a post-extract
hook.
This means that:
- we now extract the toolchain with the generic extract command,
- the toolchain is thus extracted into $(@D) ,
- fixup commands are run against $(@D), as a post-extract hook,
instead of against $(HOST_DIR)/opt/ext-toolchain ,
- once this is done, we move $(@D)/* into the final location with a
new post-extract hook.
Note: the blackfin case is special, and will be handled in a follow-up
patch.
[Thomas: register the TOOLCHAIN_EXTERNAL_FIXUP_CMDS only for the Arago
case, add some additional comments in the code about why we're moving
the toolchain around.]

The buildroot internal toolchain now adds a wrapper. When we use a
buildroot toolchain as an external toolchain, we want to bypass this
wrapper and call the compiler directly, for two reasons:
1. The options added by the wrapper are not necessarily appropriate
when it is reused as an external toolchain. For instance, ccache
may have been enabled while building the toolchain but not when
using it as an external toolchain.
2. Currently, the wrapper expects to reside in .../usr/bin, but when
used as an external toolchain it will be in .../ext-toolchain/bin.
Therefore, the wrapper can't find the real binary and sysroot
anymore.
To bypass the wrapper, we check for the existence of *.br_real files in
the external toolchain directory. If any such file exists, the wrapper
will add the .br_real suffix for all the wrapped files. Note that the
wrapper doesn't check if the *.br_real exists for each individual
wrapped file, it just assumes that all wrapped files have a
corresponding .br_real. This is currently true but that may change in
the future of course.

The toolchain wrapper will be reused for the internal toolchain, so it
belongs in the toolchain directory. Also, the ext- prefix is removed
from it. The build commands are moved to a new toolchain-wrapper.mk.
The wrapper arguments that are also relevant for the internal toolchain
wrapper are moved to toolchain-wrapper.mk, the rest stays in
toolchain-external.mk.
While we're at it, move the building of the toolchain wrapper to the
build step of toolchain-external. There is no specific reason to do
this, other than that it fits better semantically. Also remove the
MESSAGE call, otherwise we'd see:
>>> toolchain-external undefined Building
>>> toolchain-external undefined Building toolchain wrapper
/usr/bin/gcc ...
Having an extra "Building toolchain wrapper' message is pointless.
The useless condition on $(BR2_TARGET_OPTIMIZATION) is removed. It was

without that condition as well.

The mentioned commit intended to remove the passing of an mtune parameter

but the changes have the side-effect that march/mcpu is now also passed when
mtune is already given on the command-line. In that case, only mtune should

Therefore, when a uClibc-ng toolchain is used as an external

However, this is actually only true for Analog Devices pre-built

Add a new option BR2_GCC_ENABLE_LTO that builds gcc and binutils with
LTO support.
Individual packages still have to enable LTO explicitly by passing '-flto' to
GCC, which passes it on to the linker. This option does not add that flag
globally. Some packages detect if the compiler supports LTO and enable the flag
if it does.
To support LTO, ar and ranlib must be called with an argument which triggers the
usage of the LTO plugin. Since GCC doesn't call these tools itself, it instead
provides wrappers for ar and ranlib that pass the LTO arguments. This way
existing Makefiles don't need to be changed for LTO support. However, these
wrappers are called <tuple>-gcc-ar which matches the pattern to link to the
buildroot wrapper in the external toolchain logic. So the external toolchain
logic is updated to provide the correct symlink.
[Thomas:
- Add a separate BR2_BINUTILS_ENABLE_LTO option to enable LTO
support in binutils. This is a blind option, selected by
BR2_GCC_ENABLE_LTO. It just avoids having binutils.mk poke
directly into gcc Config.in options.
- Remove the check on the AVR32 special gcc version, which we don't
support anymore.
- Adapt the help text of the LTO Config.in option to no longer
mention "Since version 4.5", since we only support gcc >= 4.5 in

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

The CodeSourcery toolchains have a very interesting feature: they warn
the user when an unsafe header or library path is used, i.e a path
that will lead host headers or libraries to leak into the build.
This commit adds a similar functionality into our external toolchain
wrapper, so that it can be used with all external toolchains, and can
also be tuned as needed. By default, the external toolchain wrapper
now gives warnings such as:
arm-linux-gcc: WARNING: unsafe header/library path used in cross-compilation: '-I /usr/foo'
arm-linux-gcc: WARNING: unsafe header/library path used in cross-compilation: '-L /usr/bleh'
but the compilation continues successfully. One can then easily grep
in his build log to search for occurences of this message.
Optionally, if BR_COMPILER_PARANOID_UNSAFE_PATH is defined in the
environment to a non empty value, the external wrapper will instead
error out and abort the compilation.

Some crazy folks use MIPS machines as build machines. ;-)
On MIPS, the only acceptable hash-style is 'sysv', because the MIPS ABI
defines that the GOT ordering to be the same as the symbols ordering,
while GNU hash requires symbols to be sorted by their hash.
Looking at binutils' code, it seems that only MIPS suffers from that
limitation.
Currently, we force the toolchain wrapper to be linked with both hash
styles, which breaks on MIPS.
So, fix that by singling out MIPS, and use sysv in that case, and both
otherwise.

The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.
This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.
Alignment of line continuation characters (\) is kept as-is.
The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'
Brief explanation of this command:
^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line
\([?:+]\?=\) any assignment character =, :=, ?=, +=
\([^\\]\+\) any string not containing a line continuation
\([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a
line continuation character
\(\s*\\\) optional whitespace, followed by a line
continuation character
Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.
This expression was tested on following test text: (initial tab not
included)
FOO = spaces before
FOO = spaces before and after
FOO = tab before
FOO = tab and spaces before
FOO = tab after
FOO = tab and spaces after
FOO = spaces and tab after
FOO = \
FOO = bar \
FOO = bar space \
FOO = \
GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse
FOO += spaces before
FOO ?= spaces before and after
FOO :=
FOO =
FOO =
FOO =
FOO =
$(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
AT91BOOTSTRAP3_DEFCONFIG = \
AXEL_DISABLE_I18N=--i18n=0
After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
expression leaves the number of whitespace between the value and line
continuation character intact, but the whitespace before that could have
changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
actually makes the code more readable.
Finally, the end result was manually reviewed.

The 2014R1 toolchain is provided in two flavours by Analog Devices:
one based on gcc 4.3.x, which is considered stable, and one based on
gcc 4.5.x, considered experimental. In commit
5a65b8e185 ("toolchain-external: add ADI
Blackfin 2014R1 toolchain, remove 2012R1") both variants were added.
However, after some testing in the autobuilders, and discussion with
the Analog Devices folks, it turns out that the experimental version
of the toolchain is too experimental. It causes numerous build
failures, and the Analog Devices folks clearly say that it's an early
release and that they expect quite a few problems to show up.
Therefore, this commit removes the experimental flavor and keeps only
the stable variant. Note that the removal/renaming of the Config.in
options is not a problem, since those options were added after the
2014.05 release.

When getting the sysroot used for the kernel headers version check,
passing TOOLCHAIN_EXTERNAL_CFLAGS causes a problem when used with
multilib toolchains, where only the main sysroot has the header files,
and the other sysroots only have the libraries.
Since the kernel headers version used is normally the same for all
sysroots, this commit solves this problem by removing the
TOOLCHAIN_EXTERNAL_CFLAGS argument when calling
toolchain_find_sysroot, so that it returns the main sysroot, in which
<linux/version.h> can be found for the kernel headers version check.

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.

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.

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.

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.

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.

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.

The Xilinx Microblaze external toolchains that we had support for are
very old, and are causing a huge number of build issues. Thanks to
Spenser Gilliland, we now have support for Microblaze in the internal
toolchain backend, and the autobuilders have been using the internal
toolchain backend since then. Therefore, it's time to deprecate those
old and unusable external toolchains.

(e)glibc doesn't support a fully statically linked userspace. Even a
basic program such as Busybox fails to do authentication due to glibc
loading some libraries dynamically. Therefore, we disable the
possibility of using a (e)glibc toolchain when
BR2_PREFER_STATIC_LIB=y.

Based on a suggestion from Peter, this commit factorizes the logic and
regular expressions that are used to find the sysroot and libdir for a

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.

As Samuel Martin noticed, libthread_db is not only needed when
cross-gdb+gdbserver is used, but also when the native gdb is used on
the target. As a consequence, this patch modifies the glibc package
and the external toolchain logic to ensure that libthread_db is copied
to the target either when the native gdb or gdbserver is enabled, by
relying on the BR2_PACKAGE_GDB option, which is enabled when native
gdb and/or gdbserver are enabled.

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.

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.

Previously, an external-toolchain on a mipsel/mips64el target
didn't select the appriopriate endianness but
it asked the user to set the correct CFLAGS on his/her own.
We fix this by appending "-EL" to the toolchain wrapper options
if the user has selected a mipsel/mips64el target.
[Thomas: remove unneeded test on BR2_ENDIAN, since mipsel and mips64el
are always little-endian, and add the corresponding big endian case.]

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.

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/.

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.
