To be clear, GCC will very likely reject any port upstreaming that uses Arm64
for the same reason.  And GCC is a lot more tightly controlled.  At least if you
want upstream support.

Believe it or not I'm actually trying to help you here, the fact that clang has
called it arm64 is why we want to allow the alias.  As I mentioned before, it
just can't be the main name.
