    Expect for another variant of error message when gdbserver cannot resolve hostname
    
    I've noticed that on a few hosts, when given an invalid hostname,
    gdbserver fails with:
    
      spawn /../../gdb/gdbserver/gdbserver --once tcp8:123:2353 /gdb/build/fedora-s390x/build/gdb/testsuite/outputs/gdb.server/server-connect/server-connect
      tcp8:123:2353: cannot resolve name: No address associated with hostname
                                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
      Exiting
    
    Unfortunately, this causes a fail on the new
    gdb.server/server-connect.exp test (introduced by the IPv6 patch):
    
      FAIL: gdb.server/server-connect.exp: tcp8: start gdbserver: gdbserver should fail but did not
    
    This happens because we're expecting for another variant of this error
    message:
    
      cannot resolve name: Name or service not known
    
    Therefore, this patch extends the helper function 'gdbserver_start' to
    also recognize the "No address associated with hostname" message.
    This "fixes" the testcase on the hosts that use this variant.
