	* config.guess: Do not unconditionally run the script fragment
	to set $CC_FOR_BUILD. Put the script in the shell variable
	$set_cc_for_build and only evaluate it before $CC_FOR_BUILD is
	referenced. (Poor man's function inlining!)

	In future, the goal will be to reduce the dependence on a C
	compiler to detect system types by utilising other means.
