I assume the second "--target" statement you listed above was a typo in
the email. Otherwise the second "--target" statement should be
"--prefix". I've built a powerpc-eabi cross compiler running on linux
with gcc-2.95.2 and binutils-2.9.1 (one of three cross compilers we're
using, and I've always had to twick something). Keep in mind that
bintutils-2.9.1 is broken, at least when you build a powerpc-eabi cross
compiler.  The linker puts multiple .bss variables at the same address. 
I had to rebuild binutils from one of the later snapshots.  You might
consider downloading the same sources that MontaVista is using for their
PowerPC CDK, that way you're reasonably assured that the compiler or
linker won't be broken.
