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.
(restore-target-env-var): Iterate on reversed list, if second
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.
