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.

This commit introduces a virtual package called 'toolchain', located
in 'toolchain/toolchain', which simply depends on
'toolchain-buildroot' or 'toolchain-external' depending on the
selected toolchain backend.
For now, toolchain-buildroot and toolchain-external are still manual
make targets, but the following patches convert those backends to use
the package infrastructure as well.
In addition to this:
* The main Makefile is modified to always make BASE_TARGETS point to
this new toolchain virtual package.
* The main Makefile is changed to include all the toolchain/*/*.mk
files: the toolchain virtual package, and the toolchain-buildroot
and toolchain-external directories.
* The dependency of the toolchain on prepare dirs and dependencies is
moved to the toolchain virtual package. It is moved as a
prerequisite of the "toolchain-source" rule to ensure that all
directories are prepared before we even start extracting the
toolchain.

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.

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.

When NPTL support was introduced, gcc required a three stages build
process. Since gcc 4.7, this is no longer necessary, and it is
possible to get back to a two stages build process. This patch takes
advantage of this, by doing a two stages build process when possible.
We introduce a few hidden kconfig options:
* BR2_GCC_VERSION_NEEDS_THREE_STAGE_BUILD, which is set by the gcc
Config.in logic to indicate that the compiler might need a three
stages build. Currently, all versions prior to 4.7.x are selecting
this kconfig option.
* BR2_TOOLCHAIN_LIBC_NEEDS_THREE_STAGE_BUILD, which indicates whether
the C library might need a three stages build. This is the case for
eglibc, and uClibc when NPTL is enabled.
* BR2_TOOLCHAIN_NEEDS_THREE_STAGE_BUILD finally is enabled when both
of the previous options are enabled. It indicates that a three
stages build is actually needed.
In addition to those options, the uClibc/gcc build logic is changed to
use only a two stages build process when possible.

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.

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.

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.

Buildroot to determine whether soft float is used or not.
* Per-architecture visible BR2_<arch>_SOFT_FLOAT options, for the

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.

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.

For some reason (probably because the ARC changes modify some lex/yacc
files without updating their pre-generated variants, or because the
date/time of the pre-generated files is not correct), building the ARC
gcc requires host-flex and host-bison.
We have tested 4.2 for AVR, 4.3 and 4.4 for ARM, and none of those
need host-flex or host-bison to be installed, so only the 4.4 for ARC
seems to be affected.

Since gcc doesn't use the package infrastructure, it doesn't get all
the good generic environment variables, and forgets to get
$(HOST_DIR)/usr/bin in its PATH. This prevents gcc from finding and
using host tools built by Buildroot.
This patch therefore ensures that $(HOST_MAKE_ENV) or
$(TARGET_MAKE_ENV) are passed at the appropriate locations. It will be
useful for a later patch that makes gcc depend on host-flex/host-bison
in some situations.

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.

For the following reasons:
- it used to be broken without anyone noticing for a long time,
- it is still not fully integrated within the Buildroot set of options,
- it has not gained much traction (not even I use it),
- I've always argued that sustained development should use an external
toolchain, and not rely on building one with Buildroot,
- I did not submit any of the enhancements requested during the last
developpers' day in Brussels,
- I have neither the incentive nor the time to maintain and enhance it,
it is time to deprecate the crosstool-NG backend for the 2013.05 release.
Then, it will be entirely removed early in the 2013.08 cycle, to let some
time for those that rely on it to voice their opinions. ;-)

For ARC, libgcc is always included, even when -nostdlib is given. This is
related to some small pieces of code that are not always generated by the
compiler; a call to libgcc is used in those cases instead.

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).

Previously, the crosstool-NG backend did depend on the top-level
Buildroot's .config to detect changes in the toolchain options,
using a tentatively-clever heuristic, which also included the full
Buildroot's version string to push down to set the components' versions
strings.
In doing so, any commit in the Buildroot tree would imply a complete
rebuild of the toolchain, even in the case the toolchain options did
not change, thus being a large annoyance (to say the least).
As Buildroot never guaranteed that toolchain options would be detected,
even less handled, and that the internal backend does neither detect nor
act on toolchain options changes, and delegate that to the user, there
is no point in individualising the crosstool-NG backend's behaviour.
This reasoning also applies to the depdency on the crosstool-NG's bundled
.config file, too.
So, just drop the not-so-clever heuristic, and just build the toolchain
once, leaving to the user the responsibility to explictly ask Buildroot
to rebuild the toolchain.

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.
