With -cpu max we get a warning:
qemu-s390x: warning: 'msa5-base' requires 'kimd-sha-512'.
But dropping the -cpu max and it still runs fine.

Ok, this helps to get rid of the warnings, thus feel free to add:

However, the error still persists. I now had a closer look by running the
test with "qemu-s390x" on my z15 machine directly, and all tests are
failing! The problem happens with both, gcc v11.2.1 and clang v13.0.1. The
problem goes away (i.e. test works fine) if I compile the code with -O1
instead of -O3, or if I use GCC v8.5 instead. I'll try to find out more, but
as a temporary workaround, we could also switch to -O1 instead of -O3.
