You can set MESA_LLVM_VER in make.conf, but maybe LLVM should be added
to bsd.default-versions.mk (like GCC).

Unfortunately not, the base system does not install clang/llvm
libraries.  It would be an interesting exercise to do it the other way
around: build base with ports LLVM and binutils.  Even more interesting
would be to create ports that fetch/build/install FreeBSD base.
