branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
The following error occures in the udev init script because the kernel config
may optionally not include uevent_helper.
/etc/init.d/S10udev: line 47: can't create /proc/sys/kernel/hotplug: nonexistent directory
Work around this by not trying to access the destination if it's not available.
