[gtkada] Configure doesn't find openGL

[Pascal]

Hello,

The configure script only take in account OpenGL from GL,GL32,MesaGL values.
The GL value is for standard Unix lib and include structure.
That is suitable for OpenGL with X11 thus with MacOS all GTK must be built with X11.
I got it ok with GTK / GTKAda 3.8.

Else a new value GLQuartz or whatever should be added in configure with "-framework GLUT -framework OpenGL" instead of "-lGLU -lGL" for GTK built with Quartz.
See https://developer.apple.com/library/mac/qa/qa1613/_index.html.

Regards, Pascal.
