Probably not that helpful...

rm {nptl,linuxthreads}/configure
CFLAGS='-O2 -g -pipe --march=athlon-xp'
ASFLAGS=$CFLAGS
configure --prefix=[...] --with-headers=[...] --without-gd --without-cvs \
  --disable-profile --enable-add-ons --without-tls 

I can't build glibc without optimizations or just '-O'.

(That's the same place where GNU Mach crashes when building glibc
without '--without-tls'.)
