Under the old logic for validate_switches, once suffix or starred got set,
they stayed set for all later switches found in the spec. So for e.g.
%{g*:%{%:debug-level-gt(0):
Once we see g*, starred is set. Then we see %:, and it sees that as a
zero-length switch, which because starred is still set, matches any and all
command-line options. So targets that use such a spec accept all options in
the driver, while ones that don't reject some, such as the recent
-nostdlib++.
This patch fixes the inconsistency, so all targets would complain about
-nostdlib++, and then sets SKIPOPT for it so they don't.
gcc/ChangeLog:
* gcc.cc (validate_switches): Reset suffix/starred on loop.
gcc/cp/ChangeLog:
* g++spec.cc (lang_specific_driver): Set SKIPOPT for nostdlib++.
