Thanks.  Looking closer, I notice that swrastg is already built
everywhere except on Hurd, just not installed.  So it's probably just a
matter of adding the llvm build dependency on kfreebsd-*.

There are a few options when we package that version:

- Revert this commit;

- Use a diversion in the libgl1-mesa-dri-experimental package;

- Assume the Gallium driver is mature enough and ship it in the
  libgl1-mesa-dri package.

Nothing that needs to be decided now, though.
