will fail to build in:

gbm.c: In function ‘gallium_screen_create’:
gbm.c:54:4: error: implicit declaration of function ‘pipe_loader_drm_probe_fd’
gmake[3]: *** [gbm.o] Error 1

This is due to i915g not defining -DHAVE_PIPE_LOADER_DRM
A workaround is to add gallium_require_drm_loader statement to i915 in
configure.ac (or additionally enabling one driver that already has it).

Or one could check in gbm.c for HAVE_PIPE_LOADER_DRM before calling
pipe_loader_drm_probe_fd().
