On platforms like the Raspberry Pi the EGL implementation is not compatible with X. This means that while EGL and Open GL ES can be enabled, and will work fine with platform plugins like eglfs, EGL (and thus GL) should be automatically disabled in xcb, otherwise a compilation error will occur since xcb assumes the native handle types are the corresponding Xlib types.
