I don't think we have yet bothered to support building 3rd-party kernel
modules without also having various parts of the src tree around.

At least this was the case with Arla.  I believe OpenAFS needs src
trees for OpenBSD and FreeBSD cache manager builds too.

I could see it being hard to integrate, but using <bsd.kmodule.mk>
may make some things easier.
