New testcase c-c++-common/va-arg-va-list-type.c fails for aarch64:
...
FAIL: c-c++-common/va-arg-va-list-type.c  -std=c++11  (test for errors, line 8)
PASS: c-c++-common/va-arg-va-list-type.c  -std=c++11 (test for excess errors)
FAIL: c-c++-common/va-arg-va-list-type.c  -std=c++14  (test for errors, line 8)
PASS: c-c++-common/va-arg-va-list-type.c  -std=c++14 (test for excess errors)
FAIL: c-c++-common/va-arg-va-list-type.c  -std=c++98  (test for errors, line 8)

FAIL: c-c++-common/va-arg-va-list-type.c  -Wc++-compat   (test for errors, line

PASS: c-c++-common/va-arg-va-list-type.c  -Wc++-compat  (test for excess
errors)

The problem is that since the test-case is incorrect, an error is expected, but
the error is missing.

The error is alreay missing before the commit that introduced the test-case.
