Yes, the executables are partially statically linked,
leading to multiple copies of -ldb, one for each utility.

You can do whatever you wish.

On embedded, you can likely eliminate all the db_* utilities.

Of course when something breaks, you will be flying blind.

db_stat is useful for diagnosing locking problems.
db_verify is useful if you need to check that the rpmdb is intact.
db_dump/db_load are necessary to convert with possible format changes.

The other db_utilities are less useful.

There is also tools/db*tool.c that uses one copy of
the library and uses argv[0] for selecting the db utility.
