With the updated kernel tools, we generate a list of sccs, patches, configs and BSP definitions as part of the meta data generation.
It is valid if there aren't any of these artifacts found (i.e. you are just building a branch and a default config), but invoking the tools with no inputs isn't a good idea. To avoid this issue, we generate a string based on the artifacts and skip calling the tools if there's nothing to do.
