TSIG isn't the only thing that needs cryptographic functions. BIND also
had support for DNS COOKIES (RFC 7873), which also need openssl. I would
say openssl is not optional, so just don't compile without it.

I don't even know why there's an option to compile without openssl, but
I'm sure one of the BIND developers can enlighten us.
