This adds backports of a couple of patches necessary to support macOS
arm64 hosts for gcc. It was ported from
https://github.com/richfelker/musl-cross-make/pull/129 with some small
fixups to make the patches apply cleanly.

This refreshes the line numbers, removes any fuzz (which would make any
future forward ports easier) and standardizes the patch/file headers
(which makes them easier to read).
