Log message:
	Silently allow assignment to readonly variables, as long
	as the new value is equivalent; the old value is kept
	(remember -- new and old are equivalent, not necessarily
	the same value -- it is a structural/recursive equivalence)
	Does Quake allow recursive data structurs? If so, assigning
	a recursive value to or from a readonly value will recurse
	forever. The fix for that would be to hash up any references
	seen during the walk and stop upon a repeat.
	
	Evaluate -Dfoo=bar on the command line earlier
	These get written to m3make.args.
	That is why the change to allow readonly variables to be written.
	
	This way, you can say cm3 -DTARGET=foo.
	
	Consider not writing to m3make.args.
