No holy war here.  Johnathan and I were talking about this a couple of
weeks ago.  I agree that a non-recursive-make-solution is probably the
right path.  If you're game, I'd be delighted to accept a patch which
"does the right thing".  Automake is supposed to have (some) support for
doing this.  We thought that doing the conversion in the midst of the
migration was a bit more than we wanted to bite off.
