This patch purpose is to allow not to save the generated python bytecode in
a file for later use through the PYTHON_DONTCOMPILE environment variable.
I do not see the use of it, because you can choose if you want but it seems
somewhat related to gentoo.
Maybe useful when the generated rootfs is mounted on read-only on the target.
Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>
