We always recommend to use this syntax instead:

	${CROSS_COMPILE}gcc ...

Try running a "file test.elf" command here, followed by
"${CROSS_COMPILE}ldd test.elf".

Where is this root file system coming from? Is it built from ELDK
tools and ELDK libraries only?  Are all the needed libraries (see list
from ppc_4xx-ldd above) installed?

Maybe you have the native ldd command installed and can use this foir
checking?

Best regards,
