mysql_tzinfo_to_sql in galera distribution adds "SET SESSION wsrep_replicate_myisam"

The mysql_tzinfo_to_sql tool included with Galera distributions of MariaDB gives this as its first line of output:

SET SESSION wsrep_replicate_myisam=ON;

That is problematic since, wsrep_replication_myisam is not a session variable. This means that the tool will fail with this error:

ERROR 1229 (HY000) at line 1: Variable 'wsrep_replicate_myisam' is a GLOBAL variable and should be set with SET GLOBAL

Perhaps this should be used instead:

SET SESSION wsrep_on=0;
