glibc 2.28 release on August 1st and extended ABI freeze for ppc64le float128.

Community,

The next release of glibc 2.28 is planned for August 1st.
We normally enter a global ABI/API slushy freeze on July 1st.

Both IBM and Red Hat have a strong desire to see the IBM ppc64le
transition to the new long double format without having to wait an
additional 6 months until we have another release.

For example I want these changes in Fedora 29 so we can showcase the 
latest IBM POWER9 hardware.

I'm willing to extend the ABI/API freeze to July 13th for the ppc64le
float128 changes, to allow those to go into the glibc 2.28 release.

This would leave us with 2 weeks of testing for most arches, and I
can make sure we get good testing coverage during those two weeks from
the set of hardware Red Hat has access to, and the Red Hat glibc team
doing builds and tests on x864_64, i686, ppc64be, ppc64le, s390, s390x,
armv7hl, and aarch64.

I'm not suggesting we move the August 1st release, but just decrease
the window of the ABI/API freeze, and restrict it to only the changes
we accept as such e.g. ppc64le float128 changes.

Does anyone object to this?

Cheers,
Carlos.
