Hmmm ... I don't have that exact configuration handy to try, but
we know that PG works against OpenSSL 1.1.1a in principle, and
it does work for me with FreeBSD 12.0-RC1 from mid-November,
which contains
# openssl version
OpenSSL 1.1.1-freebsd  11 Sep 2018

The error you quote looks a bit like bad decisions in PG's configure
script --- maybe you need to re-run configure?  Be sure to blow
away any autoconf cache file if you're using one.
