[Bug target/35508] New: [avr] 4.3.0: undefined reference to `__ffshi2'

["dmixm at marine dot febras dot ru" <gcc-bugzilla at gcc dot gnu dot org>]

The next program is not linked (-Os option):

  int ffs (int);
  int main (int argc, char *argv[])
  {
    (void)argv;
    return ffs (argc);
  }

with undefined link to '__ffshi2'.

The used libc library (Avr-libc project) contains the ffs() funcion.
