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.

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.

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

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>

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.

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.

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.

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.

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.
