This sort of thing is better asked on the e3-hacking list rather than
direct to me.

gcc is the obvious cross compiler to use. I believe there are numerous
guides around for building it in a cross compiling configuration, but
there are at least 2 options that make it easier:

* buildroot (http://buildroot.uclibc.org/)
  This is what Mark's image (the one you can download) is built using.
  Fairly quick to get going; you can use the BR_config in
  E3_release_v1.tar.gz

* OpenEmbedded (http://www.openembedded.org/)
  This is a lot more involved to get going, but does offer a huge number
  of packages. It's the basis for Familiar (the iPaq distro) and
  OpenZaurus and David Ford's patch to support the E3 (including
  building u-boot and the kernel) was recently added to it.
