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].
