OK, I guess we need some better wrapping of compat code.

Check out arch/ppc64/boot/Makefile, in particular CROSS32_COMPILE. The
boot wrapper is a 32bit binary. 

Now that the toolchain is biarch capable we could get rid of that and
use gcc -m32 instead. But for the moment specify a CROSS32_COMPILE ant
things should link.
