[gtkada] Building GtkAda git master on OpenSuSE Tumbleweed

Seems like you might want to simply use

   ./configure --without-GL  --prefix=...

when you configure, to disable openGL support altogether, rather than the "hack" you just did.

Seems like an installation issue here.

Strange that this would not be included by pkg-config, though. We cannot hard-code this in
GtkAda, since gtk+ doesn't depend on X11 for all supported systems.

Thanks for the feedback
