+There is a parallel make build issue in src/egl/drivers/dri2/
+for wayland builds. Can be reproduced with:
+
+$ rm src/egl/drivers/dri2/*.h src/egl/drivers/dri2/platform_wayland.lo
+$ make -C src/egl/ drivers/dri2/platform_wayland.lo
+
+../../../mesa-18.1.2/src/egl/drivers/dri2/platform_wayland.c:50:10: fatal error: linux-dmabuf-unstable-v1-client-protocol.h: No such file or directory
+
+This patch adds the missing dependency.
