since V4L1 is no longer provided by the kernel, the user space header has been removed. so udev now build fails:
extras/v4l_id/v4l_id.c:31:28: fatal error: linux/videodev.h: No such file or directory
make: *** [extras/v4l_id/v4l_id.o] Error 1
simple fix is to not build that code anymore
Backported v4lv1 removal patch from udev-167.
