Thanks for the input. I currently exclusively use OpenSSL in base, so I was
hoping there was something sane and similar to control using base vs.
security/openssl, like the WITH_OPENSSL_PORT and WITH_OPENSSL_BASE knobs,
only for libressl. It looks like security/openssl is still on 1.0, so I
might be able to get phantomjs working with security/openssl and continue
using base for other ports.
