if you use a target of *-softfloat-* the glibc ebuild will add --without-fp 
and the gcc ebuild will add --with-float=soft

the Gentoo ebuild does nothing of the sort ... this is all in the glibc build 
system itself

glibc-2.4 on ppc will require gcc-4.1.x ... anything older is not supported 
and i certainly wont waste any time on it

well, once upstream settles on something i have no problem cutting a patch 
from their cvs and putting into our glibc-2.4 patchset ... but i wouldnt 
really want to do anything until they've settled on a solution first
