Hearing nothing, I have studied more this stuff today and applied the
patch down to 9.5.  Based on the first reports from the buildfarm,
things are getting interesting with steamerduck complaining that the
input and the output do not match in the test:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=steamerduck&dt=2020-07-22%2006%3A01%3A24

The package of libz used there seems to be 1.2.11, so that's up to
date:
https://software.opensuse.org/package/libz1

I am not exactly sure what this environment does differently.  There
are other machines using s390x, so I'll wait a bit more before doing
something.
