classes/cml1: ensure -c menuconfig forces a rebuild next time
Ensure the following results in the kernel being rebuilt, repackaged and re-deployed in the final step: bitbake virtual/kernel bitbake -c menuconfig virtual/kernel [ make changes to the kernel configuration and save ] bitbake virtual/kernel If there are no changes to the configuration saved, the rebuild will not be triggered. Note that this relies on a function recently added to BitBake and requires full hashing (i.e. BB_SIGNATURE_HANDLER must be set to a signature handler that inherits from BasicHash) - if this is not the case or the function is not available in the version of BitBake being used this change will do nothing. Fixes [YOCTO #2256].
