I'm unsure. I've googled a bit and found stuff saying that Apple used
to use arm64, but now everyone uses aarch64. I don't know if the
original patch had ever actually been tested on an ARM Mac.

If Roland Kaufmann doesn't respond with a better plan, I suppose we'd
be safest just adding it as you suggest.
