Yes, you're right : there is no "vote" and don't even know why people
started to do that :-)
James will be able to give a status update, but I know for sure that
both builds are in good progress on both big and little endian sides.
Regarding older power cpu support, that will be completely different,
and (even if I'm only a sysadmin) can lead to tears and cry :-)

Afaik, EL7 code for ppc64 is optimized for Power7 (and so can work on
Power8), and ppc64le started with only support for Power8. So that
means that if someone wants to have it working on older arch, one has
to start with a parallel build/package set, starting with glibc itself.
That reminds me some "adventure" when I was trying to build some ppc
packages on my old Mac for IBM iSeries machines :-)
