BUG #14308: Postgres 9.5.4 does not configure against OpenSSL 1.1.0

The following bug has been logged on the website:

Bug reference: 14308
Logged by: Jeffrey Walton
Email address: noloader(at)gmail(dot)com
PostgreSQL version: 9.5.4
Operating system: OS X
Description:

OpenSSL 1.1.0 does not use SSL_library_init. Instead, it uses
OPENSSL_init_ssl.

$ ./configure --with-openssl --with-includes=/usr/local/ssl/include
--with-libraries=/usr/local/ssl/lib
...

Results in:

checking for SSL_library_init in -lssl... no
configure: error: library 'ssl' is required for OpenSSL

Relevant entry from 'config.log':
