Second patch to bring cross-compilation support to python build-system.
Allow the libraries detection routine to look for headers and libs in
other directories than /usr/include or /usr/lib through the env variables
PYTHON_MODULES_INCLUDE and PYTHON_MODULES_LIB.
We can then use it to look for libraries in the buildroot staging directory.
Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>
