egl_fbdev_swrast.so should load api_*.so under /usr/local/lib/egl/ for client
API support.  You should not see this warning.  You may want to check if the
client APIs are there, and try again with eglinfo from the demos repo.

Your app should open the fb device and pass the fd (casted to
EGLNativeDisplayType) to EGL.

egl_dri2 driver in master only supports X11.
