[PATCH] distutils3: Avoid MACHINE specific checksums

[Richard Purdie <richard.purdie@linuxfoundation.org>]

The MACHINE variable is used to handle sysroot paths within one of the
patches to python3-native. In this context, it is relocation safe and
the resulting packages should not have MACHINE specific checksums,
therefore excluding MACHINE in this context is safe.

This whole setup is ugly and ideally we should come up with a better
way of handling this but at least allow a stop gap solution for now.
