[PATCH] fontconfig: fc-arch: Support fat builds (OSX) so the cache isn't detected as corrupt when switching archs

[Jeremy Huddleston]

I don't have commit access to fontconfig, so could some else please  
push this?  Without it, fontconfig uses the same cache files for  
different archs (and sees the cache as corrupt when switching archs).
