Looking to resolve Qemu on AppleSilicon build failure

[Blake Garner]

I was able to build qemu on my m1 mini with the port from the linked PR!
Should be able to test it and confirm hvf is working as expected this week.
Also I ran into an issue similar to https://trac.macports.org/ticket/60189
when trying to use the Xcode 12.5 Beta 2 command line tools to build the
qemu port. Reverting to the Xcode cli tools 12.4 worked.
