openSUSE/SLE builds (was: OpenLDAP 2.4.49 available, LMDB 0.9.25 available)

Also I maintain builds installing in separate prefix /opt/openldap-ms and with reduced feature set (e.g. no back-bdb and no back-hdb): https://build.opensuse.org/package/show/home:stroeder:openldap/openldap-ms Please test.
