Actually, as I recall (it takes a while to page all this stuff back into my brain), the J2SE 5.0 Makefiles for HotSpot actually were completely separate for PPC vs. i386+x86_64, and we just had a final make rule that lipo'd the different architectures together at the end. The PPC "side" of the Makefile machinery ran fine on an Intel builder though.
