TokuDB plugin cannot be enabled

When trying to install TokuDB with SELinux

MariaDB [(none)]> install soname 'ha_tokudb';

ERROR 1126 (HY000): Can't open shared library /usr/lib64/mysql/plugin/ha_tokudb.so' (errno: 2, cannot enable executable stack as shared object requires: Permission denied)

The executable stack flag has to be cleared since the library doesn't require it, which obviously triggers SELinux permission issue.

execstack -c /usr/lib64/mysql/plugin/ha_tokudb.so will clear the flag and make the library loadable again.
