another proposol to fix the zic -l bug

[Ulrich Drepper]

Hi,

could the appended patch be considered for the next tzcode release?
It is an IMO cleaner rewrite since it preserve the old semantic and
allows the symlink function (which isn't available on SysV) be skipped
by defining a simple symbol.

Thanks,
