When no X11 headers are present eglplatform.h will break unless
certain defines are set prior to its inclusion.
including wayland-egl.h defines WL_EGL_PLATFORM which will stop
the attempted inclusion of the X11 headers.
Maybe this isn't the best solution to the problem, but it's harmless
and gets the job done.
