Looks like the Makefile might need some work. I see stuff for handling
aach64/arm64, so it SHOULD work, but there are things I don't understand
about AARCH64 to figure it all out. Still, it should be detected.

Out of curiosity, if you do a "make -C  /usr/ports/devel/llvm10 config",
the line for BE_NATIVE should show the architecture you are running on. If
it's missing/something else, maybe you should ask brooks@ about it.
