Bruno added the issymlink and issymlinkat inline functions to Gnulib to
make code like this easier to understand:

    char dummy[1];
    if (0 <= readlink (dir, dummy, 1))
      {
         /* Handle symbolic links here.  */
      }

This patch converts the few cases used in coreutils.

Will push tomorrow, unless there is any objections.

Nice cleanup.

thanks,
