Add support in Python build system to specify host pgen

Python needs a "pgen" program to build itself. Unfortunately, the

Python build system assumes that it can use the pgen program it has

just built to build itself. Obviously, this cannot work in

cross-compilation mode since the pgen program have been built for the

target.

Therefore, this patch adds support in the Python build system for the

new PGEN_FOR_BUILD variable, so that we can point Python ./configure

script to the 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, and then ported to

python3.3 by Maxime Ripard <maxime.ripard@free-electrons.com>

Do not look at host headers/libraries in cross-compile mode

When we are cross-compiling, setup.py should never look in /usr or

/usr/local to find headers or libraries. A later patch adds a

mechanism to tell setup.py to look in a specific directory for headers

and libraries.
