Compiling Plataform Preferences on Ubuntu 16.04

[Kevin Rushforth]

This is really about gcc rather than a version of Ubuntu.

I see little value in making the javafx.graphics native code compile 
with such an old version of gcc that it doesn't support C++11. (Worth 
noting that WebKit requires an even newer version, since it uses C++20 
features).

So, while yes, I'd like to see this continue to be buildable on Ubuntu 
16.04 -- and so far I have no problems compiling on that OS -- it seems 
fine to require a newer compiler in order for you to do so.
