We can almost do it automatically. scripts/sort-config has a mode to check for options changing state from what we set them. But it gets confused by the way we do overrides and thus spews a bunch of false positives. so if we did a pass through the generated file post merge.pl, but pre oldconfig, to weed out the duplicates (just keep the last version of every symbol), I think we could just pass the result to sort-config -m to find out what's getting changed. it still won't catch the 'bool became tristate' in all cases, but if there's a dependant symbol as there was in this case, it should get flagged.
