Note that `clang-dxc` is just `clang --driver-mode=dxc`. The situation here is equivalent to calling clang with a triple for a target you haven't built. I guess we could technically avoid creating the symlink if there aren't any compatible targets, but I don't really think that would be worthwhile.
