This adds support for building on Ubuntu armhf by building OpenSceneGraph with OpenGL ES 2.0. To do this, two build dependencies needed to be added: libegl1-mesa-dev and libgles2-mesa-dev. libgl1-mesa-dev isn't needed for OpenGL ES, and so it has been excluded from armhf.

In addition, a patch that changes the method of selecting what version of OpenGL/OpenGL ES contained a change that excluded one of the examples from being built under certain conditions. That part of the change is included here (as it would otherwise cause a build failure).

Note that OpenSceneGraph will still FTBFS, but will fail at a later point. This is because one of the examples uses freeglut, which still uses OpenGL. The option of building freeglut with OpenGL ES is still in the trunk and is expected to be released with version 3.0. While this example could be temporarily excluded, any application that uses both openscenegraph and freeglut will still FTBFS. The intention for this MP is so that when freetype 3.0 is released, only that package's packaging will have to be changed.
