Building OpenJFX on clean install of CentOS 7

[Kevin Rushforth]

The current toolchain for building JavaFX is gcc 8.2. As long as you 
don't build WebKit, it will still build with gcc 5.4.

I just tried it on an Oracle Linux 7 machine with gcc 4.9.1 (which is 
what we used to use a couple years ago), and the build fails for me with 
the same error. Looks like you will need a newer gcc.
