Subject: 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.

Subject: Expand external toolchain wrapper to custom flags

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.

Subject: external-toolchain: details on selecting the multilib variants

Each multilib variant need to be selected using a special combination
of flags, requiring specific choices of the Buildroot options. This
commit documents those configuration choices to make it easier to use
the various multilib variants.

Subject: external-toolchain: run checks even on extracted toolchains

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.

Subject: 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.
