This libc ld.so special handling for hardware capability is used by

MMX, intel's multi media extension, is also same circumstance that
both Pentium (i586) and Pentium MMX (i586 MMX) are 'i586 class
processors'.
This bit is a good idea but...

Let's not do anything about this until someone gets clarification from
GCC that -march=i686 is not actually supposed to be a 686, OK?
Why? Even if gcc didn't use cmov with -march=i686, is there another
facility for using cmov in an optimized library? IOW, this ld.so
extension sounds like something useful regardless of the state of gcc.
