Right now the net/relayd port always statically links libressl.  This is a
problem because relayd also links libmd, and this weird combination of
dynamically linked libmd and statically linked libcrypto means that libmd
provides the implementations of hash functions used by LibreSSL.  Problem is,
they're not quite compatible.

I wrote a patch for the upstream port, but because net/relayd is causing
problems by statically linking libressl, it might be more correct to fix it
here.  Some more details here:
https://github.com/markjdb/relayd/commit/7372b73f645418c81c5c4ec88d877dbdca9e52c2

Basically, net/relayd should also move "-lmd" to the end of the LDADD line.
