#     
#      - run the checker (e.g. sparse) after the compiler
#     
#      - remove unneeded cc-option tests for old compiler flags
#     
#      - fix tar-pkg to install dtbs
#     
#      - introduce ccflags-remove-y and asflags-remove-y syntax
#     
#      - allow to trace functions in sub-directories of lib/
#     
#      - introduce hostprogs-always-y and userprogs-always-y syntax
#     
#      - various Makefile cleanups
