Your patch is missing the following hunk:

diff --git a/tests/tcg/s390x/Makefile.target b/tests/tcg/s390x/Makefile.target
index 16b9d45307..54e67446aa 100644

With debian11, I can build the tests. However, mie3-sel seems to have an issue:


  TEST    mie3-compl on s390x
  TEST    mie3-mvcrl on s390x
  TEST    mie3-sel on s390x
timeout: the monitored command dumped core

qemu-s390x gets killed via

"Program terminated with signal SIGILL, Illegal instruction."
