That's a big patch..

I don't see the point of the sort-by-relpages code. The order the
objects are dumped should be irrelevant, as long as you obey the
restrictions dictated by dependencies. Or is it only needed for the
multiple-target-dirs feature? Frankly I don't see the point of that, so
it would be good to cull it out at least in this first stage.
