That sounds almost identical to the Linux/ELF BuildId support, for
which I found a rather detailed explanation at
https://fedoraproject.org/wiki/Releases/FeatureBuildId .

I see that there's an open ticket to add --build-id support to
mclinker, so it should be straightforward for FreeBSD to switch to
build-id after we bring mclinker into the base system.
