Once again, the problem does not occur at build time.

libgbm.so built with the problematic if disabled:
martyj:~/Build/Mesa-7.11-rc3/lib$ nm /usr/lib/libgbm.so | grep dri
000017a0 t dri_bind_extensions
00003ca8 d dri_core_extensions
00001730 t dri_destroy
00001b30 t dri_device_create
00001ca0 t dri_fd_get_driver_name
00001870 t dri_load_driver
00001480 t dri_lookup_egl_image
00003a60 d driver_map
00003ca0 d gbm_dri_backend
000015d0 t gbm_dri_bo_create
000014e0 t gbm_dri_bo_create_from_egl_image
000016f0 t gbm_dri_bo_destroy
00003cc0 d gbm_dri_device_extensions
000014b0 t gbm_dri_is_format_supported

libgbm.so built from the RC3 tarball:
martyj:~/Build/Mesa-7.11-rc3/lib$ nm libgbm.so | grep dri
         U gbm_dri_backend

Result when running application with the faulty .so
martyj:/usr/lib/gbm$ firefox
/usr/lib/firefox-5.0.1/firefox-bin: symbol lookup error: /usr/lib/libgbm.so.1: undefined symbol: gbm_dri_backend
