[Bug c/38308] New: -Wformat does not work for wide strings

[bonzini at gnu dot org]

GCC does not warn for this:

int main()
{
  wprintf (L"%s", 5);
}

GCC should try converting the string to single-byte (e.g. to UTF-8, which would
work for any wchar_t encoding in which 0-127 maps to char's encoding) and test
the format string.
