python: bump to 2.7.6

Browse Source 
Even though jumping from 2.7.3 to 2.7.6 looks like a minor version
bump, it is in fact a fairly significant one, because a good number of
changes to help cross-compilation have been merged into Python
upstream. Therefore, most of our patches are affected by this change.

In detail, this commit:

 * Renames all the patches to follow the naming convention of patches
   in Buildroot: the patch file names should not have any version
   number.

 * The patches numbered above 100, that add configuration options to
   disable certain modules of the Python standard library, are only
   renamed and slightly adapted, they didn't change that much.

 * The patches numbered below 100 are almost entirely rewritten: many
   of the cross-compilation problems that used to exist in Python
   2.7.3 no longer exist, and the number of remaining problems is
   smaller, and can be fixed with smaller patches.

distutils: fix build_ext check to find whether we're building Python or not
The build_ext logic uses
sys.executable.startswith(os.path.join(sys.exec_prefix, "bin")) to
determine whether we're building a third-party Python extension, or a
built-in Python extension. However, this check is wrong in
cross-compilation mode, and instead, the sysconfig.python_build
variable should be used.
