Greetings, Alan!

Seems tha current Makefile works only under GNU Make 4.x, but Ubuntu
14.x contains an older one (3.x). I made a commit to develop branch of
GoVPN. Can you check if it works correctly? If so, then I will make a
new release.

% git clone https://github.com/stargrave/govpn.git
% cd govpn
% git checkout develop
% make

Happy hacking, Sergey Matveev
