Okay I did a ppc64 build with the testsuite:
http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=1731757
and reproduced #8849 and (probably) #8819 too.

I say "probably" since my ppc64 testsuite results are littered with
"Actual stderr output differs from expected:" warnings caused by:

"""

I only see those on ppc64 so far.
Perhaps there is some way to ignore those?

In #8819 I reported test failures in an unregisterised compiler produced on

I reproduced also on s390x:
http://s390.koji.fedoraproject.org/koji/taskinfo?taskID=1369051
including #8819 unfortunately !!

So seems this happens on ppc64, s390x and x86_64 for unregisterised.

I know "unregisterised" may be considered less supported these days
but this seems quite serious and I hope it could still be fixed for 7.8.1.
