Bug#640874: leave: debian/rules is not a Makefile

[Josip Rodin <joy@debbugs.entuzijast.net>]

Since my reasoning here didn't seem to leave a particular positive dent with
those tech-ctte members who have responded so far, I would just like to
solicit Ian Jackson's input, given his role in defining and implementing the
debian/rules calling convention originally. In other worse, if I can't
convince the original author of a non-make-dependent API that the API isn't
make-dependent, there is no recourse but to yield :)

Or if my memory serves me wrong and it was instead some other person,
particularly one that isn't intricately involved with Debian or can't be
reached any more, I'm also done.
