Support targeting macOS aarch64 in older GCCs
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. Signed-off-by: Steven Fackler <sfackler@gmail.com>
