I would like to tweak glibc so that it only builds one POWER 620/970

This does not affect ppc64le in any way.
The reason for this change is that the ppc64 builders are awfully slow
as of late, and the multiple builds (four times currently) currently
make ppc64 the slowest architecture to build by quite a margin.
Any comments?
I think the reason for keeping lower bound as powerpc 970 is Apple G5
as the last desktop class hw, with Talos II as the next viable desktop
solution coming I would even vote for having power8 as the base line
for ppc64 for some next Fedora version. Even when new developments are
done in the ppc64le flavour, ppc64 has it's value in for example easier
debugging big endian related issues. Until then ppc970 + power8
variants would be good enough (IMO).
