I noticed those myself too, it was just a few though, so I manually
recompiled as soon as I ran into them.  But it's all C++-related, so

grep libstdc++ $EPREFIX/var/db/pkg/*/*/NEEDED.MACHO.3

should give you a list, I guess you can narrow down into, by using
scanmacho -r on the binaries from those matches, if they reference
gcc/arm64-apple-darwin21/12.2.0, you'll need to rebuild.

Something like 

% grep -l libstdc++ $EPREFIX/var/db/pkg/*/*/NEEDED.MACHO.3 | sed "s:${EPREFIX}/var/db/pkg/::" | cut -d/ -f1,2 | xargs qlist -o | grep '/bin/' | xargs scanmacho -BF '%F|%r' | grep "gcc/arm64-apple-darwin21/12.2.0" | cut -d'|' -f1 | xargs qfile | cut -d: -f1 | sort -u

(you could use that in emerge -1av `...` I guess :))
