Just to add, the ability to build clang against an installed LLVM tree would make it significantly easier for the FreeBSD LLVM and Clang ports to switch to using CMake.  This would make us very happy, as our build infrastructure automatically uses Ninja by default for CMake ports, so we'd get a nice speedup on package builds.
