Yes. When I remove `libbsd-devel` I get:

/usr/bin/ld: /home/azul/azul/criu-git/criu/apparmor.c:127: undefined reference to `strlcpy'
/home/azul/azul/criu-git/criu/crtools.c:130: undefined reference to `setproctitle_init'

Besides that no package should break (despite only its testcase) when some additional system feature is available.
