<pre>In MacPorts, our clang ports build and install libclang_rt* from compiler-rt,
and the STL header from libc++, but NOT the libc++ runtime.
With the autoconf-based build system, this "just works", but with cmake, it
looks like we don't have a way to accomplish that. The STL headers are
installed if libc++ is present in the source tree, but building and installing
libclang_rt and libc++ are controlled by the same cmake variable
(LLVM_BUILD_RUNTIME).</pre>
