dtinfo/mmdb: redo the way this library is built

Specifically:

- use libtool so that the top level library contains the actual
  objects, and not just the sub-archives, which the linker will just
  ignore.
- create the source files via symlinks rather than referencing them
  with relative paths.  Doing it that way causes a 'make clean' to
  delete objects in DtMmdb/ which is wrong.
- fix up utility/ - it seemed to be building more source files than
  the original Imakefile listed.  Other changes may need to be done
  here if similar mistakes were made in other subdirs.
