You mentioned elsewhere that you are only focussing on libc++,
libc++abi and libunwind for now. Lets say libc joins this scheme
sometime in future. Can one do:

$> cmake ../runtimes
-DLLVM_ENABLE_PROJECTS="llvm;clang;clang-tools-extra;libc" <...>

The libc build currently needs llvm in all modes. For linting, we need
clang and clang-tools-extra.
