You already found a solution (adding {virtual}), but here is an
explanation:  The toplevel recipe wants to build "inst-kernel" and you
define an "inst-kernel" target in the child kernel/main.aap.  Since the
items in a child recipe are relative to that recipe, you actually define
the target "kernel/inst-kernel", viewed from the toplevel recipe.
