Ah, I didn't realise that. I assumed llvm-16.0.0-aarch64.tar.gz was a
cross compiler. I'm sure you documented that in the page but hey who
reads the documentation ;)

Makes sense now. But I still think it's good style that a tarball named
llvm-16.0.0-aarch64.tar.gz extracts to llvm-16.0.0-aarch64.

Yeah, sharing the load is always good.
