Well, what a waste of time :-)

Based on what I've seen with -Os on the pmax I would have expected a
little more.  Maybe the i386 has fewer optimisations that take up more
space than the mips, but that theory would take a lot longer on my pmax
to test that the 2-odd hours the peecee took to do a "make build" :).

Anways, if we miss a single disk floppy install by about 5 or 6kB, it's
an option...
