tried after "rpm -bi --target=athlon glibc.spec" and set
LD_LIBRARY_PATH=/var/tmp/glibc-2.2.93-root/lib:/var/tmp/glibc-2.2.93-root/usr/lib

used the glibc srpm, a 12M file

standard RHL build:
26.01user 0.06system 0:26.23elapsed 99%CPU
  (107major+1632minor)pagefaults 0swaps

athlon build:
25.73user 0.10system 0:26.10elapsed 98%CPU
  (108major+1632minor)pagefaults 0swaps


Nothing major there, but I'm not sure the build is what
I want. It still created /lib/libc.so.6 and /lib/i686/libc.so.6
and uses the one in i686.
