Any particular reason you excluded the powerpc tests? Going by a quick count,
powerpc has 32 of the 54 self tests, ie. more than half.
Sorry I didn't get a chance to review v1 or v2, but is this really the best
solution we can come up with? It seems to involve a lot of boiler plate getting
repeated in every Makefile.
I'm off this week so I can't immediately come up with something better, I'll
try in the new year.
