[issue34007] test_gdb fails in s390x SLES buildbots

I requested a SLES VM in https://linuxone20.cloud.marist.edu as indicated by @David Edelsohn (the builtbot maintainer) and I can reproduce the issue on master, 3.7, 3.6 and 3.5. So it seems that a change in gdb itself caused this. Interestingly, in Python 3.5 the error is different:

======================================================================
FAIL: test_threads (test.test_gdb.PyBtTests)
Verify that "py-bt" indicates threads that are waiting for the GIL
