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).

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.

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.

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.

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.

When the mechanism that allows Buildroot to download external
toolchains automatically was added, all the sanity checks on the
external toolchains were not performed. This commit re-enables those
checks that we already do on external toolchains that are not
downloaded/extracted by Buildroot. This makes the toolchain checks
more consistent accross various configurations.

The BR2_TARGET_OPTIMIZATION flags were not used by the external
toolchain wrapper, which broke the multilib selection logic of
multilib external toolchains. It also simplifies the compilation of
external programs since all flags are properly passed automatically by
the toolchain wrapper.

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.

When the external tools chain is installed in a path that match one of
the first case test, all symlink are created to the external
wrapper. The proposed solution is to test only the base name not the
full path.

Some CodeSourcery toolchains contain a huge number of locales that are
not useful, even though they account for 70-80% of the total toolchain
size. By skipping the extraction of those useless locales, we make the
toolchain extraction process slightly faster, and also make the output
directory size a lot smaller (host/opt/ is 213 MB instead of 1.5 GB
with a 2010.09 ARM CodeSourcery toolchain).

The recent commit adding the external toolchain wrapper has broken the
support for external toolchain. The check_arm_eabi, check_cplusplus
and check_cross_compiler_exists functions were using TARGET_CC, which
points to the toolchain wrapper, but at the moment those functions are
called, the wrapper hasn't been generated yet.
We fix this by passing to these functions the path to the C or C++
compiler they should use for their tests.

Now that we use a wrapper for external toolchains (and internal ones
default to the correct setting), we no longer need to explicitly pass

Add a simple toolchain wrapper for external toolchains, which forces the
correct sysroot/march/mtune/floating point options needed to use it
with buildroot.
With this in place the external toolchain behaves similar to the internal
ones, and the special handling can be removed. This also means that the
toolchain is usable outside buildroot without having to pass any special
compiler flags.
Also adjust the downloadable external toolchain support to install under
HOST_DIR so it can be used after the temporary build files are removed.
