I know how Makefile dependencies work, thank you.  The point I was
trying to make was that all the sophisticated Makefile solutions to
support parallel builds are nice, but they are useless to us unless
someone provides a complete patch which includes correct dependency
handling.

I like the original patch (except for the small check install
oversight), since it's simple and I can convince myself that it is
correct.  I'm not sure it is needed right now though.  One example
would be that it has the potential to break patches applied when
building packages.
