It depends :-). Some software, and possibly the majority of software,  
compiles without problems using '-arch i386 -arch ppc'. Software that  
does configure-time checks for byteorder will cause problems unless  
the build environment knows about universal binaries (Python is an  
example of that, python 2.4.4 and 2.5 build as universal binaries  
even though the configure script checks for the byteorder of the host  
machine).
