Fixes to the builds of any of the tools to make this easier would be
greatly appreciated.  I don't actually need to do cross builds for
ia64, but do for powerpc64 where I frequently get things wrong and end
up using a glibc that was built separately.

This all ties in with the tutorial that Robert Schiele is giving at the
GCC Summit <http://www.gccsummit.org>, which will further enlighten us.
