This patch triggers a failure on the autobuilder:

http://autobuilder.yoctoproject.org:8010/builders/p1022ds/builds/246/steps/shell_59/logs/stdio

(its reproducible, this is the second one now)

I suspect there is a missing DEPENDS += "kern-tools-native". 

You'd be able to reproduce this with a:

bitbake busybox kern-tools-native; bitbake busybox kern-tools-native -c clean; bitbake busybox

Cheers,

Richard
