[PATCH] D39520: [libcxx][CMake] Fix libc++ build when no LLVM source tree is available.

[Zachary Turner via cfe-commits]

The reason I ask is because I remember several months ago when I originally
made these changes, there was quite a bit of difficulty because some of the
Jenkins builders were wanting to run libcxx tests without any llvm source
tree on the machine.

Does this configuration still exist, or is it gone?  If it is gone, I think
many libcxx maintainers would be very happy if they can assume the presence
of an LLVM source tree somewhere on the disk.
