[issue45881] Cross compiling on Linux is untested, undocumented, and broken

[Christian Heimes]

Christian Heimes <lists at cheimes.de> added the comment:

bpo-45886 addresses the cross build issue with freeze_module command.

The wrong header files come from the fact that setup.py uses CC variable from sysconfig instead of environment. The sysconfig variable contains the C compiler of the build interpreter instead of the host interpreter. The correct value is in os.environ.
