What about adding this dependency in image.bbclass? Otherwise, the 
kernel will not get built if it's not pulled in by other packages like 
v86d. For example, if we build core-image-minimal for qemumips, the 
kernel is not built by default and we have to `bitbake linux-yocto' 
before we can use `runqemu' to start target.
