[PATCH xserver] hw/dmx: fix build without GLX

[Rob Clark]

Fixes this compile break that showed up on arm recently:

dmxinit.c:746:26: error: 'glxSupported' undeclared (first use in this function)
dmxinit.c:746:26: note: each undeclared identifier is reported only once for each function it appears in
