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].
