sorry for spamming, but

also when entering .bm-work/rock where buildman failed and doing just my

	make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

in that directory created by buildman, produces perfectly fine images.
(buildman does create the .config, so I'm just finishing the build, buildman
failed at for unknown reasons)
