mdadm needs ansidecl.h which is provided by binutils. If binutils is not built or it is rebuilding while mdadm is building you get this: http://autobuilder.yoctoproject.org:8010/builders/nightly-ppc/builds/410/steps/shell_105/logs/stdio It may be possible to remove the dependency according to this post, if that's what we would prefer: http://comments.gmane.org/gmane.linux.raid/38468
Removal is preferred and we've already started doing this: http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=37cf162998b13d7d594c7ed68c47d440a3033ed5
