[UBUNTU 20.04] zlib not working on all s390x systems configurations

[bugproxy]

Pull request (https://github.com/madler/zlib/pull/410) and tagged https://github.com/iii-i/zlib/tree/dfltcc-20200511.

The new code contains the following improvements:
* Added support for switching between software and hardware compression.
* Added --dfltcc configure flag (the old way of building it still works).

Switching between software and hardware compression is not simply a nice-to-have feature, but is actually required by Java - that's why we are requesting an update.

Did I got it right that the "being able to switch between software and hardware compression _feature_" is at the same time the _fix_ for the issue with Java?
And would that only need to be added to focal/20.04 or also to other Ubuntu releases?

This is correct.

zlib acceleration has been added with https://bugs.launchpad.net/ubuntu/+source/zlib/+bug/1823157 to 19.10, so the fix should go there as well. Earlier versions are not affected.

Ok, thx.

Note that Ubuntu 19.10 reaches EOL in just over a month, so this may not
wind up being fixed in that release.

Changing the Eoan entry to Invalid, since Eoan reached it's EOL:
