I have tried this on the simple hello.c module.
I use the ELDK cross compiler to generate code for
a ppc 440 from an X86 based machine. It fails
with some emulation mode problems, any ideas ?

[root@basher ebonymnt]# export CROSS_COMPILE=ppc_4xx-
[root@basher ebonymnt]# make -C /home/simon/ebonymnt/linux-2.6.10 M=`pwd`
make: Entering directory `/home/simon/ebonymnt/linux-2.6.10'

Did anyone develop a resolution to this problem?

Tray this

It's work

You should call

make CROSS_COMPILE=ppc_4xx- -C ...

instead of your command

CROSS_COMPILE=ppc_4xx- make -C ...

which handles make variables differently. See the make manual for details.
