- fix build against security/openssl on FreeBSD-10
in case port is build with tinderbox or poudriere.
openssl is registered as BUILD/RUN dependency not
as LIB dependency, therefore the check for openssl
fails since it will be installed in a later stage
by tinderbox / poudriere.
Thanks to Katsuya Higuchi who noted this issue on
the apache@ mailing list.
