[Piglit] [PATCH 06/10] piglit-dispatch: Use eglGetProcAddress if PIGLIT_HAS_EGL but not GLX

[Daniel Kurtz]

If EGL is defined, we could use the eglGetProcAddress to lookup extension
proc addresses.

Note, however, that eglGetProcAddress does not work for
core procs [0].  Returning NULL will cause the process to crash... but
shouldn't we be using piglit for EGL dispatch, anyway?

[0] Unless the driver also supports EGL_KHR_get_all_proc_addresses.
