Building for x86 on ppc also works if the software being built is  
careful
about build vs. host programs and so and so forth (cross-compilation).

But what I meant was that it is unsupported in MacPorts (not on Mac  
OS X),
mostly due to all the +powerpc and similar target stuff being totally  
off...
