I need a generic tool since I build code for PPC variants, some with
and some without a floating point unit.

The above looks like it explains how to produce a gcc that doesn't
have floating point, but I'm more concerned about producing *glibc*
that doesn't have an floating point in it.  I can't see how modifying
the t-ppcgas file in gcc(since I'm using gas) can affect the code
genereated when building glibc.  I must be missing something here.
