I think bootstrapping a cross compiler by cross building libc++abi and libc++ is a pretty generic use case.
Pulling in all of LLVM's cmake modules depends on top of libc++abi hinders cmake detection when cross building libc++abi standalone.

You said before that we needed this for the sanitizer.
Do you know why libc++ doesn't need to import this?
