Bug Description

Galera tests are skipped on some Jenkins slave, because the following check:

${MYSQLD} --basedir=$MYSQL_BASEDIR --user=$USER --help --verbose --wsrep-sst-method=rsync| grep -q wsrep
probe_result=$?
if [[ "$probe_result" == "0" ]]
    then
        vlog "Server supports wsrep"
    else
        skip_test "Requires WSREP enabled"
fi

fails. The reasons is that if there's a default system-wide my.cnf with query_cache enabled, starting mysqld --wsrep-sst-method fails as follows:

131112 12:50:18 [ERROR] WSREP: Query cache is not supported
   (size=16777216 type=0)
131112 12:50:18 [ERROR] Aborting

So the above check assumes there's no Galera support and skips the test.
