Execute ln command with GNU compatible options

    On some OSX macport installation, GNU commands may be used in favor
    of native commands and 'make install' fail with
         'ln: invalid option -- 'h'"

    As BSD ln support the GNU -n option as an equivalent of the -h option
    it shoud be preferred over the specific BSD option.
