You might want to look at the existing --with-universal-archs=ARCH in 
configure for how this is done for OS X builds.  It's probably both 
simpler and more complicated than would be needed elsewhere: on OS X, a 
single file can contain object codes for multiple architectures, e.g 
32-bit and 64-bit, rather than having to have multiple files.
