get it to cross compile gcc (to run on ppc).  Does anyone
know of a good HowTo to do this?

I'm currently downloading the source distro of ELDK, so if
it's already in there I'll find it, but if there is one
elsewhere online please let me know.

Very good, full of features.

My favorite cross tool chain site:

Building and Testing gcc/glibc cross toolchains
http://kegel.com/crosstool/

Look into Canadian crosses.  At the very least you should find the
discussion helpful.

I'd use the ELDK if I were you as an x86 hosted cross compiler, if only 
because it makes sense in terms of compiling bootloader & kernel with 
the same toolchain. Also, if memory serves the ELDK comes with a powerpc 
gcc in the supplied ppc root file system.

Alternatively : you can use the uClibc toolchain, to generate a similar 
setup.

Here's a script I've thrown together since I sometimes need to generate 
gcc toolchains easily for various targets. I've tested it with arm and 
powerpc and because, it might be useful to switch between c libraries. ymmv.
http://netsoc.dit.ie/~deckard/software/build_compiler.sh. This script is 
based on some excellent documents that Red Hat produced.
