libEGL.so may call functions in libGL.so, which are not part of OpenGL
API.  For example, when you call eglCreateWindowSurface to create an
EGLSurface, libEGL.so might in turn call st_create_framebuffer in
libGL.so to create the real surface.

Because of this, you can not take libEGL.so from vendor A and take
libGL.so from vendor B, and expect them to work together.
