This was there before, but:
AFAICT, this rule will succeed even if one of the subdir relink targets
fails, because the shell will keep going to the next iteration of the
loop.

        set -e; for i in $(SUBDIRS); do ...; done

seems to do the trick, and properly fails as soon as one of the subdir
commands fails.

Cheers,
Julien
