gpu-viv-bin-mx6q: Respect X11, DirectFB, FrameBuffer distro features
As we cannot allow concurrent build of applications targetting
different backends we use the distro features to package the need
libraries for the backend. Currently it does:
X11 support, if 'x11' feature is enabled
DirectFB support, if 'x11' is not enabled AND 'directfb is enabled
FrameBuffer, fallback
As 1.1.0 version of the Vivante libraries are build against DirectFB
1.4 we cannot support it for now, so we explicitly disable it for this
version so it is easy to add it back when new version, supporting
newer DirectFB, is released.
