gcc-dg.exp (${tool}_load): Handle non-existing set_target_env_var the same as if it is empty list.

	* lib/gcc-dg.exp (${tool}_load): Handle non-existing
	set_target_env_var the same as if it is empty list.
	(dg-set-target-env-var): Fix up error message.
	(set-target-env-var): Record both preexisting env var values
	as well as info that env wasn't set.

	sublist element is 1, setenv the env var to the third sublist
	element, otherwise unsetenv it.
	(gcc-dg-runtest): Don't initialize set_target_env_var.
	(dg-test): Unset set_target_env_var if it was set.
