If the string starts with a '*' then the '*' should be stripped and the
rest of the string output without further processing (see
ASM_GENERATE_INTERNAL_LABEL in tm.texi).

Else we need to apply STRIP_NAME_ENCODING, then emit the user_label_prefix
and the stripped name.

  char *realname;

  STRIP_NAME_ENCODING (realname, NAME);
  if ((NAME[0] == '*'))
    dyn_string_append (STR, NAME[1])
  else
    {
      dyn_string_append (STR, user_label_prefix)
      dyn_string_append (STR, realname);
    }
}
