My make-fu is not strong enough for that - which is why thats the bit
I nicked from the entropy.ch scripts!

Another option which may be doable for someone with more knowledge of
make would be to build binaries for all architectures seperately (you
can build i386, ppc, x86_64 and ppc64), and then use lipo to glue them
together.
