The list of libraries in LDLIBS was generated from the DEPDIRS-xyz variable. This is valid when the subdirectory name match the library name, but it's not always the case, especially for PMDs. The patches removes this feature and explicitly adds the proper libraries in LDLIBS. Some DEPDIRS-xyz variables become useless, remove them.
