   This looks like --with-cpu wasn't given to configure. The spec patch 
should add this, but you also have to do this if building without 
rpmbuild. Even to build an standard x86 glibc, I found things work best 
if I use --with-cpu=i686.

   MY main workstation blew up on Friday, and it turns out it'll be 
locked up in the shop (it was under warranty still) till next week. 
That's my primary build machine, with most of my modified tool chains, 
glibc, and other build stuff are located. I don't have enough disk space 
on this laptop to build glibc. :-( I can go grab the machine (video card 
less) if you need me to look into this in the next day or so, but I'd 
prefer to wait for the replacement video card and power supply if possible.

   The geode patch must be in sysdeps/i386/i686, not in i585. For the 
Geode support, it only configures correctly if the geode sub directory 
is in the i686 directory.
