With none of build, source, full or tarball in PACKAGECONFIG,
kernel-devsrc still builds and installs, but the package is only the
/usr/src/kernel link to an empty tree. Nothing fails until someone
tries to use it on target, and then it is not obvious why.

Skip the recipe with a message instead, so an image that installs
kernel-devsrc fails at parse time and says which PACKAGECONFIG
is missing.
