lang/adacontrol: Reaction to gcc-aux upgrade to gcc49
While the version remains the same, AdaControl comes with two flavors of
distfiles: "old" and "new". The "old" distfile was appropriate for
gcc47-aux, but the "new" one is required for the gcc49-based ada compiler.
This change updates the distfile to be used to build adacontrol.
Add new port: lang/adacontrol
Adacontrol is a tool that analyzes language constructs in Ada programs. It
can be used as a standalone tool, or integrated into other tools. An
example of integration can be seen with the upcoming devel/ahven port.
