kern-tools: add buildall and robustness fixes

Updating the kern-tools SRCREV to pickup the following functionality:

 - buildall: provides the ability to build all kernel branches
             without a build system, only a cross compiler and configme
             are required.

 - robustness/cleanups: obselete/unused code removal and general robustness
                        fixes from Paul Gortmaker and Bruce Ashfield

The following kern-tools commits are part of this series:
