Joshua Henderson cbe725d755 eudev: prevent udev init script nonexistent directory error
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.

# udev This is a minimal non-LSB version of a UDEV startup script. It
# was derived by stripping down the udev-058 LSB version for use
# with buildroot on embedded hardware using Linux 2.6.34+ kernels.
#
# You may need to customize this for your system's resource limits
# (including startup time!) and administration. For example, if
# your early userspace has a custom initramfs or initrd you might
# need /dev much earlier; or without hotpluggable busses (like USB,
# PCMCIA, MMC/SD, and so on) your /dev might be static after boot.
#
# This script assumes your system boots right into the eventual root
# filesystem, and that init runs this udev script before any programs
# needing more device nodes than the bare-bones set -- /dev/console,
# /dev/zero, /dev/null -- that's needed to boot and run this script.
