Done - it would be easier not to have two designations anyway.
the canonical triple is aarch64-*-darwin* (that is agreed between the config.*
folks and the Apple OSS folks).
However, of course, the end users know the port as “arm64” and that’s the arch
tag that has to be applied (but I think we can most likely keep it out of
config stuff).

thanks - this is what I pushed:
[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.
Signed-off-by: Iain Sandoe <i...@sandoe.co.uk>
gcc/ChangeLog:
* config.host: Add support for aarch64-*-darwin.
* config/aarch64/host-aarch64-darwin.c: New file.
* config/aarch64/x-darwin: New file.
