The Ubuntu diff contains a change that was likely done to workaround 
this issue:

aflplusplus (4.04c-2ubuntu2) lunar; urgency=medium

  * Disable lld support on s390x for now, making the build fail.

It's not at all clear why it says: "failure in tests".

The pasted tests are only the cmocka tests.
The test failure is in the "afl++ test framework".
Its log says:

Hi,

It's not at all clear why it says: "failure in tests". All the test seem
to pass. Other architectures also have the "not all test cases were
executed" message.

I've tried to build it again on the buildds, but it failed the same way.
