Bug 444481

With valgrind 3.18.1 on Fedora 34 s390x with:

glibc-2.33-20.fc34.s390x
gdb-10.2-3.fc34.s390x
gcc-11.2.1-1.fc34.s390x
binutils-2.35.2-6.fc34.s390x

I am seeing the following failures:

gdbserver_tests/hgtls                    (stdoutB)
gdbserver_tests/nlsigvgdb                (stderr)
gdbserver_tests/nlsigvgdb                (stderrB)
gdbserver_tests/nlvgdbsigqueue           (stderr)
gdbserver_tests/nlvgdbsigqueue           (stdoutB)

Which I don't observe on RHEL8 s390x with:

glibc-2.28-167.el8.s390x
gdb-8.2-16.el8.s390x
gcc-8.5.0-3.el8.s390x
binutils-2.30-108.el8.s390x

The f34 log files:
