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.
