[PATCH] D38057: Try again to fix libcxx CMake so that it doesn't break when no LLVM source tree is available

This actually **breaks** using external lit. It no longer respects `-DLLVM_EXTERNAL_LIT` passed to CMake, and instead forces the hardcoded libcxx path, which — since the file listed there doesn't exist — causes fallback to also-non-existing `llvm-lit` to happen.
