In my case a leftover CFLAGS=-O0 in /etc/make.conf was the culprit
('=' instead of '+=' not being a typo). As another side effect, build
world took about four times as long as usual, before it errored out.

While at it, I of also ran into what's described
in
https://lists.freebsd.org/pipermail/freebsd-current/2018-December/072531.html,
before removing DEBUG_FLAGS from /etc/make.conf.


Conditionalizing the flags to only be pulled in for the directories I
actually wanted them to be relevant for would certainly have helped.
