You'd be surprised...I've actually had a cross-compiler on my m68k for
another (different) m68k target. Sounds dumb, but it was necessary at the
time (and took FOREVER to build initially).

That is a good idea, but bear in mind that embedded targetted toolchains
may be better compiled even on the slowest archs (you never know who may
want one or why).
As for 64->32 bit cross-toolchains, I agree. I've run into quite a few
problems going the other way as well. Problems may be inevitable in those
cases. FWIW, I did have one alpha->i386 toolchain somewhat working once,
but have since deleted it since I built up the i386 system that was in
pieces in my house :-)
