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>

Subject: [PATCH] Darwin, aarch64 : Initial support for the self-host driver.
|
|
|
|
At present, there is no special action needed for aarch64-darwin
|
|
this just pulls in generic Darwin code.
