Hmm... I didn't finish that hazzle to get this (old) e500 cross-toolchain
working. (Well, my knowledge wasn't very detailed at that time.)

Instead I managed to get an up to date _native_ toolchain which is IMHO
quite simple to maintain.
(gcc-4.2.1, binutils-2.17, latest (e)glibc, latest kernels)
My mpc8540 development platform has a harddisk on pci and can be
used like a normal workstation now...

It should work... hence you will end up with a quite old toolchain.

That's an double precision instruction of the e500 core which your
binutils don't recognize. You are using either the wrong binutils or an
too old version of your binutils. binutils-2.15 should have it:

Dan or Kumar can give more details here.
