if you're trying to bootstrap a new platform, cross-building *some*
development tools can be pretty useful.

in this case, though, i don't think yat2m qualifies.  The bootstrap
itself doesn't need documentation -- once you've bootstrapped, you can
re-build natively and the native re-build can include the documentation
development tools.
