On powerpc the answer is also simple. Having too many sets of libraries is
a maintainance nightmare and build time killer (ppc/ppc64 glibc already
builds twice to three times as long as i?86/x86_64, having 3 extra sets of
libs would mean waiting for glibc to build forever). And the gains aren't
very noticeable.
Oh, yes I know that. I was just explaining that the optimized library
mechanism that glibc has extends to things other than SSE. I wasn't asking
for more tuned libraries.
