Comment (by michaelld):

 Yes! I've done this with quite a few ports and in my limited testing they
 work the same on ARM64 as on x86_64. I use `gh` a lot, and it works quite
 well on ARM64 with this small tweak to the Portfile. I'd love to see it
 natively built, but there is a whole chain of dependencies to fix for
 ARM64 ... so, this solution is way and by far the fastest to get ARM64
 support for many current ports that otherwise will take months to get
 working.
