Comment (by kencu):

 Yes -- we'll have to clean that all up. LLVM-9.0 might build arm64; it's
 pretty well written that way. clang-9.0 might also, but compiler_rt in
 clang-9.0 needs some cleanup to build for arm64.

 What is asking for llvm-9.0? ld64 should want the +xcode variant, so not
 that.

 I have llvm-devel just finishing an update now, and if it succeeds I'll
 push that tonight. That is the most likely thing that will build on arm64
 right now, and I guess I'll pull out the supported_archs from that and let
 -'er-rip and see what happens.

 I had llvm-11 / clang-11 all set to go but got into a huge fight (once
 again) with the GitHub PortGroup and the GitHub PortGroup won, so I gave
 up on that for now while I figure out how I'm going to defeat it.

 That should probably build i386/x86_64/arm64 too.
