wsrep_certification_rules: Define as a weak global symbol. While there are separate _embedded.a for statically linked storage engine plugins, there is only one ha_innodb.so which is supposed to work with both values of WITH_WSREP. The merge from 10.0-galera introduced a reference to a global variable that is only defined when the server is built WITH_WSREP. We must define that symbol as weak global, so that when a dynamically linked InnoDB or XtraDB is used with the embedded server (which never includes write-set replication patches), the variable will be read as 0, instead of causing a failure to load the InnoDB or XtraDB plugin.
