	  Sets the linux.bootargs.machine_id global variable with a value of

	  id. It is a hash over device-specific information provided by various
	  sources.

	  Note: if multiple sources provide hashable device-specific information
	  (via machine_id_set_hashable()) the information provided by the last call
	  prior to the late initcall set_machine_id() is used to generate the
	  machine id from. Thus when updating barebox the machine id might change.

	  Note: if no hashable information is available no machine id will be passed
