Title: Ensure --mysql option works even if Postgresql is installed on the system

This commit ensure you can set --with-mysql flag even if PGsql is installed on the system. Before this patch there's no way to force compilation with MySQL if you have PG installed.

"brew install sphinx --mysql" now really add the "--with-mysql" to the configure options even if PG is installed.
