Support some customisation on python compilation.
With this patch, we can now remove some modules introducing external
dependencies from the compilation, thus removing these irrelevant in most
cases dependencies (ie. openssl, ncurses, etc).
This modules can be removed by listing them in the PYTHON_DISABLE_MODULES
environment variable.
Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>
