Cross-compiling python-3.5.x fails with "Parser/pgen: Parser/pgen: cannot execute binary file" (CBUILD="x86_64-pc-linux-gnu" and CHOST="armv7a-hardfloat-linux-gnueabi").

python-3.5.x requires "pgen" and "_freeze_importlib" to be compiled and executed at build time. Otherwise, it fails with "Parser/pgen: Parser/pgen: cannot execute binary file".

You may need this patch: https://hg.python.org/cpython/rev/0f7a299c6d50

Hmmm. Solves half the problem. Still fails when trying to run "_freeze_importlib".

This works though:

Gonna close it since it seems to be related to
