Thanks for submitting this enhancement!

For those of us using Homebrew and using the LLVM installation from
there, we get:

$ cc --version
Homebrew clang version 12.0.1
Target: arm64-apple-darwin20.5.0
Thread model: posix
InstalledDir: /opt/homebrew/opt/llvm/bin

So maybe we could add another case for "Homebrew clang"?
