We currently have an invalid IFUNC resolver in libgcc.a on POWER

I'll be on PTO next week, and it does not seem likely that this is going
to be resolved upstream before that. If upstream (both glibc GCC are
involved) don't come up with a solution, I'm not sure
If we downgrade glibc to 2.25 in rawhide, we will have to rebuild at
least the following packages right after that because they have a
GLIBC_2.26 symbol version dependency:
inn-2.6.1-6.fc27.src.rpm
remctl-3.13-4.fc27.src.rpm
sudo-1.8.20p2-1.fc27.src.rpm
tmux-2.5-1.fc27.src.rpm
unbound-1.6.4-1.fc27.src.rpm
xorg-x11-server-1.19.3-6.fc27.src.rpm
Besides the glibc downgrade, I'm not aware of anything else we could do
to get ready for the mass rebuild in time.
So, I had a look at
https://bugzilla.redhat.com/show_bug.cgi?id=F26FTBFS,
and the situation is not good :( There's 621 open bugs on that list,
and it's quite likely most of those packages will FTBFS on 27 too.
All packagers should pitch in to reduce this list before the mass rebuild
starts.
