mariadb requires rebuild after running reclaim

[p-b-west (Peter West)]

Frequently (possibly always) after a reclaim, I see this:

--->  Scanning binaries for linking errors
--->  Found 10 broken files, matching files to ports
--->  Found 1 broken port, determining rebuild order
You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt: mariadb-10.5 @10.5.13

Rebuild proceeds without problems, but why is the rebuild so frequently required?

I don't know whether 'port rev-upgrade' would behave differently.
