Did you really update the "cross binutils" which are actually contained
in the ELDK?  I would be much surprised if you did that.

What version of linux-2.6-denx are you actually trying to compile?

Also, ELDK 4.2 is already somewhat old, did you try using the
powerpc-e500v2 version of ELDK 5.3?  For example it has newer
binutils...

Cheers
