the old work around for this was removed from our glibc package. Turns
out, the binutils fix was not as much of a fix as was previously thought...
binutils-2.21-4:
- new snapshot from 2.21 branch
- add upstream patch to stop nopl usage on i686
glibc-2.13-3:
- rebuild to remove nopl instructions

glibc is probably the only package that needed rebuilt to remove those
instructions as its build forces --mtune=i686 when --march=i686 is used.
Those package that listen to --mtune=generic are fine.
As an FYI for people who were affected by this. I have had reports that
a Via C3 Nehemiah now works and that an AMD Geode required a kernel
rebuild with these to no have a kernel panic on boot but then seemed fine.
