I would tag it with both, just to be on the safe side. A poorly- 
written configure script could easily build a different universal  
binary on a PowerPC Mac than it would on an Intel Mac. It doesn't hurt  
to always record the arch of the machine that did the build, and might  
at some point prove useful.
