clang does not handle %Z on print, and just suppressing -Wformat-invalid-specifier might trigger another warning for extra arguments (since %Z is ignored). So suppress -Wformat-extra-args as well. For tst-fphex.c a heavy hammer is used since the printf is more complex and clang throws a more generic warning. Reviewed-by: Sam James <sam@gentoo.org>
