[Mesa-stable] [PATCH v2 18/27] st/omx: fix building against X11-less setups

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

The vl_*_screen_create API properly falls back to a NOP when we're
building without specific platforms. So the only thing we need is to
handle the lack of X11/Xlib.h and provide a dummy Display define.

Christian,

Do you prefer if we should print an error message, error out, or
continue with the other platform if the requested one is missing?
