Yeah, this might be doable.  It does mean generating a lot of
Makefiles that we hope nobody will use.

Right now automake only has a very primitive notion of cross-directory
dependencies.  The only ones are hard-coded -- config.status stuff and
also ansi2knr.  At least, in the sense I think you mean.  Header files
are "handled", but only by adding dummy rules to prevent trying to
rebuild missing headers.
