No, not quite.  What I want is to build 32-bit apps for a PPC64, i.e., the 
same multilib idea as 32-bit Firefox on an x86_64.

f2c, for example, won't build at all in 64-bit mode.  Building with 
--target ppc builds the 32-bit version, but sticks the libs in the wrong 
place.

So I guess my real question is: how does this whole multilib thing go 
together?
