	  Specify a space-separated list of scripts to be run after the build

	  This gives users the oportunity to do board-specific cleanups,
	  add-ons and the like, so the generated files can be used directly
	  without further processing.

	  These scripts are called with the target directory name as first and
	  only argument. Make sure the exit code of those scripts are 0,
	  otherwise make will stop after calling them.
