I would like to tweak glibc so that it only builds one POWER 620/970
libc for ppc64, and not multiple libcs with POWER6/POWER7/POWER8
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.
Builds on POWER now fail fairly consistently due to this kernel bug:
I'll keep trying, but the failure rate has gone up considerably in
recent weeks (perhaps additional builders were updated to broken
kernels?). I'm not even sure if it is below 100%.
The Fedora kernels have been fixed and are in testing now, so I think we
just have to wait. 8-(
