We possibly could support something like this, but there is value to supporting --emit-llvm even if the target backend isn't built.  Currently all the Clang tests run on all platforms, which is nice for catching accidental breakage.  When hacking on Clang, I personally don't build all the targets most of the time because it just slows me down.
