This bit of info seems to be what you are missing.

I don't know the best way to do it, but you could have another
Makefile that sets MAKEFLAGS appropriately, and then does the '$(MAKE)
-f Makefile.nova'. That seemed to work when I tried it, though since
Makefile.nova just does a $(MAKE) I got into an infinite loop :). It
did find the included .mk file, though.
