Doesn't Build on Ubuntu 14.04

libmysqlclient-dev is installed. I don't observe "MYSQL_SERVER_PUBLIC_KEY" in the MySQL headers. CloudFoundry uses Ubuntu 14.04.

Ubuntu 14.04 with 2016-06-20 Swift and 'swift build' yields:

apt-get install libmysqlclient-dev

Start with Sources/MySQL/MySQL.swift, especially the reported failures around the MySQL option identifiers, and reproduce the issue with swift build on Ubuntu 14.04 using the installed libmysqlclient-dev headers. Compare the identifiers available through those headers with the ones referenced by the source; done means the project builds successfully in that environment.
