[Buildroot] [PATCH 1/3 v2] toolchain/external: add Linaro ARM 2014.11 ARMv7 EABIhf

This toolchain has a kind of hstory of its own... ;-(

First released in November 2014, it was completely broken, and Thomas
opened a bug report. Here's the story (for reference):
    https://plus.google.com/+ThomasPetazzoni/posts/SjFkrX3ow5M
    https://bugs.linaro.org/show_bug.cgi?id=862

since then, the release has been re-done, and the issue reported above
has been fixed. This makes that toolchain almost usable by Buildroot,
with just a few little nits:

  - it is available only for x86_64 hosts

  - the toolchain is split in three parts:
    - the main archive, with the tools and a minimalist sysroot with
      just the strictly required stuff (e.g. just the C library and most
      libs as static libs, i.e. no shared libs but libc.so)
    - a secondary archive, with the complete sysroot , duplicationg most
      previously existing files in the minimal sysroot, above
    - a tertiary archive, with the 'runtime' content (whatever that
      could mean...); that one seems completely unnecessary for
      Buildroot.

  - the sys/types.h headers from the main sysroot is correct, while the
    one from the secondary archive (thus overwriting the main one) is
    broken, as it removes the definition of caddr_t (why? WHY?).

  - there's a stray backup file for libstdc++

So, add this new toolchain with three post-extract hooks, one to extract
the secondary, sysroot archive, the second to restore sys/types.h to a
useable state, and the third to remove the backup file.

(Note: we're doing it in three hooks, because the cleanup hook is
different for the AArch64 toolchain, coming soon...)
