Apple provides two mechanisms for this, one is fat binaries, which
have been supported since NeXTSTEP 3.2 (Mac OS X 10.4 == NeXTSTEP
6.4), and the other is Rosetta, which runs PPC code in emulation.
NeXTSTEP/Apple uses gcc for everything, so building fat binaries is
just a matter of figuring out the gcc options.

The .pd_linux extension has been working fine for 10+ architectures,
I don't see why Mac OS X needs more than one. If people want to
distribute binaries for the different architectures, I think it will
be easier to just put the files in properly labeled directories (ie.
Having more file extensions will mean I will have to modify the Pd-
extended build system quite a bit to make it work for that new
extension. This will take a lot of time, and probably introduce some
bugs, and I can't see any benefit.
