Thanks Bill. First try points to a depreciated page:

http://www.gentoo.org/proj/en/base/embedded/cross-development.xml

which in turn points to something more recent:

http://www.gentoo.org/proj/en/base/embedded/handbook/

A quick read looks promising, other than a statement that says some
combination of tools might not work and no way to tell until you try.

None the less I should be able to play some games and maybe just
compile something very small and see if it runs, etc.

Thanks for the pointer.

Cheers,
Mark
