That's good - does cctools now have real 64 bit support (ie. are they
trying to make the code 64 bit clean -- previously we had to compile
the whole thing with -m32)?

What do we lose if we just build everything for, say, i386?  PPC Macs
are a bit long in the tooth now aren't they?

My thought for this one is can we rebuild these files just from a
table of the exported symbols?  (ie. nm *.dylib)

Doesn't odcctools provide something to do this?
