If you're new to embedded Linux, I  strongly  recommend  NOT  to  use
bleeding   edge  tools,  but  some  more  stable  softweare  instead.
Especially GCC-3.0.3 is probably not a good choice here...

These are probably all because of problems with your setup  of  cross
develpment tools, especially GCC-3.x

This option is not supported on 8xx.

You probably want to build a "pImage"  file  (make  pImage)  instead,
which  can  be used with PPCBoot - for older kernels it gets built in
arch/ppc/mbxboot/, now it's in arch/ppc/boot/images/ .

Replace "cc" by "$(CC)" in the Makefile, and make sure CC  points  to
your   cross   compiler.  You  may  also  have  to  add  a  "#include
<linux/fs.h>" to cmds.c .

PPCBoot?
