RFC Kernel configuration check for recipes

Add the capability for other recipes to verify that kernel configuration options they depend upon at runtime are present, and warn if they are missing. This seems functional enough to me but is still in RFC - please let me know if it looks OK to you or I've missed anything (no doubt there are recipes we could add the checks to, I refer mainly to the mechanism itself).

Please review the following changes for suitability for inclusion. If you have any objections or suggestions for improvement, please respond to the patches. If you agree with the changes, please provide your Acked-by.
