The vivante EGL headers don't honor MESA_EGL_NO_X11_HEADERS, and generally seem
to assume X if no other defines are specified. Defining EGL_API_FB for the
affected platform plugins gets around the X11 defines--I had to patch qt
sources (shown below). I ran into more issues after getting around this error,
but this should get you moving:

Perhaps it would be best to patch the vivante headers to define EGL_API_FB if
MESA_EGL_NO_X11_HEADERS is defined.
Hope that helps.
