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.
