All the difficult issues supporting multi-arch are going to be with  
distutils, not Python itself.

On OS X it isn't all that hard to support (beyond backwards  
compatibility issues) because you run gcc once with the right options  
and get a single universal binary as output.  It would be a lot more  
invasive if GCC had to be run multiple times and the products had to  
be put in different places.
