2016-03-16	OPENGL: Resolve OpenGL functions on run-time.	Johannes Schickel
	Formerly we relied on static linkage. However, in the presense of modern OpenGL (ES) implementations it is not easily identifable which library to link against. For example, on Linux amd64 with nVidia drivers and SDL2 setup to create a GLES 1.1 context one would need to link against libGL.so. However, traditionally GLES 1.1 required to link against libGLESv1_CM.so. To prevent a huge mess we simply resolve the OpenGL functions on run-time now and stop linking against a static library (in most cases). GLES support needs to be enabled manually on configure time for now. Tizen changes have NOT been tested.
