Avoid using refs as hash keys. * lib/Automake/Variable.pm ($_traversal): New. (reset): Reset $_traversal. (_new): New attribute 'scanned'. (%_vars_scanned): Remove. (traverse_variable_recursively) (traverse_variable_recursively_worker): Use $_traversal instead of %_vars_scanned to detect recursively defined variables.
