You're going to need multiple configures and multiple build directories to do it that way. You may want to try just setting your CXXFLAGS to "-arch i386 -arch ppc -arch x86_64" or something.

Out of curiosity, why are you trying to build ToT 3-way FAT for OSX? It's already built like that on the system.
