I did try that at first but at the time there were no released version of
anything with the support in place.  Since I had to dig into and learn about
how gcc works I ended up doing all myself anyway.  I've learnt a lot from this
project in the last couple of months!

Yes, great minds think alike; I did just that!  It's a shame a lot of packages
are broken with respect to cross compiling, especially python!  I did hope I'd
be able to cross-compile a working ARM/iWMMXt/NPTL/EABI based Gentoo (stage1 at
least)!
