the locate dbs mentionned isn't the one at /var/db/locate.database
(updated by weekly(8) and used by default by locate(1)), but the ones at
/usr/lib/locate/src.db and /usr/X11R6/lib/locate/xorg.db (installed by
the OS at install time).

$ locate -d /usr/lib/locate/src.db:/usr/X11R6/lib/locate/xorg.db libc.so
base74:/usr/lib/libc.so.98.0
base74:/usr/share/relink/usr/lib/libc.so.98.0.a

The method used for reporting unknown files using pkg_check is
relatively simple. If you want a more elaborated tool, you could use
sysclean(8).

The method used by sysclean(8) is explained at
https://kapouay.eu.org/notes/sysclean-intro/ .
