I've done it with distcc by adding the -m32 option to cflags. I used a script 
(named after the compiler on the gentoo box) to call the compiler with the -
m32 flag and placed on the PATH environment (just for the distccd service) 
before anything else and it worked. I got a 64 bit arch box to compile for a 
32 bit gentoo (not nearly as fast as compiling locally on the arch box but 
much faster than the gentoo box). It should work similarly with other cross-
compile scenarios.
