Maybe the trick is to check whether _getopt_long_only_r is present to the
linker, in which case we can provide our own declaration of it and avoid
the AC_LIBOBJ([getopt1]).  That will make applications using argp
lighter-weight when compiled on GNU/Linux, since they aren't replacing
what is already there.
