Thanks, committed with minor tweaks (see below).

The devtmpfs dependency is not really an issue as we already depend on
it for dynamic /dev handling.

This doesn't really make sense to show here, so I moved it
target/generic where the user selects the /dev handling method. This
line would only be shown in situations where he couldn't select udev
anyway (as he hadn't selected BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_UDEV).

udevd now needs to link with librt as it calls mq_getattr() (which isn't
automatically done on uClibc), so I added UDEV_CONF_ENV += LIBS='-lt'
