Thomas Petazzoni 2455c89bab python: bump to 2.7.2
This is mostly a mechanical bump, with a refresh of all the patches to
accomodate the offsets, and some minor conflict resolution.

Add support in Python build system to specify host tools
Python needs a Python interpreter and a "pgen" program to build
itself. Unfortunately, the Python build system assumes that it can use
the interpreter and pgen program it has just built to build
itself. Obviously, this cannot work in cross-compilation mode since
the interpreter and the pgen program have been built for the target.
Therefore, this patch adds support in the Python build system for the
new PYTHON_FOR_BUILD and PGEN_FOR_BUILD variables, so that we can
point Python ./configure script to the Python interpreter and pgen
program that have been previously built for the host.
Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>, and
later significantly reworked by Thomas Petazzoni
<thomas.petazzoni@free-electrons.com>, with some inspiration taken
from the Python patches of the PTXdist project.
