You can have your own recipe that has PROVIDES = "virtual/kernel" (and would 
also need to be selected in configuration as the PREFERRED_PROVIDER of that) 
but that only installs the headers. You'd probably do well to use the 
linux-dummy recipe as an example (meta/recipes-kernel/linux/linux-dummy.bb).

Cheers,
Paul
