Thanks. With this patch, most of the ppc4xx compile problems I have noticed 
are gone now. But unfortunately not all. Those two 4xx platforms still don't 
compile:

CRAYL1 EXBITGEN

$ ./MAKEALL CRAYL1
Configuring for CRAYL1 board...
ppc_4xx-ld: cannot find common/env_embedded.o
make: *** [u-boot] Error 1
ppc_4xx-size: './u-boot': No such file

A quick scan reveals that both ports have one thing in common. They both 
include:
  common/env_embedded.o(.text)
in their linker scripts.

Cheers,
Stefan
