Thomas Petazzoni 7e960dc9da python: bump to 2.7.6
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.

Change the install location of _sysconfigdata.py
The _sysconfigdata.py module contains definitions that are needed when
building Python modules. In cross-compilation mode, when building
Python extensions for the target, we need to use the _sysconfigdata.py
of the target Python while executing the host Python.
However until now, the _sysconfigdata.py module was installed in
build/lib.<arch>-<version> directory, together with a number of
architecture-specific shared objects, which cannot be used with the
host Python.
To solve this problem, this patch moves _sysconfigdata.py to a
separate location, build/sysconfigdata.<arch>-<version>/, and only
this directory gets added to the PYTHONPATH of the host Python
interpreter when building Python modules for the target.
