RPi compiling Icecast with support for openssl

In the Raspbian repositories, the Icecast2 package does NOT support encrypted connections via openssl. If you try to use the ssl tags in the /etc/icecast2/icecast.xml configuration file, Icecast will fail to start. You'll see something like this in /var/log/icecast2/error.log: 

[2016-10-15 20:41:45] INFO connection/get_ssl_certificate No SSL capability.
