This is a rebuild to remove nopl instructions on i686 so those "i686" 
processors (e.g. Via C3 Nehemiah) that do not support it do not crash a 
lot.  This issue was supposed to be fixed upstream in binutils-2.21 so 
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...

  - new snapshot from 2.21 branch
  - add upstream patch to stop nopl usage on i686

  - rebuild to remove nopl instructions

 > objdump -d /lib/ld-2.13.so | grep nopl | wc -l

 > objdump -d /lib/ld-2.13.so | grep nopl | wc -l

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.

Signoff both,
