[Piglit] [PATCH 05/10] piglit-dispatch: only use glXGetProcAddressARB if PIGLIT_HAS_GLX

[Daniel Kurtz]

If there is no GLX, then there is no glXGetProcAddressARB to call and the
library can't link.

Returning NULL for the proc address might cause some tests to crash - but
they shouldn't they be using waffle anyway for EGL dispatch?
