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
