Sorry, my point is that it is likely that we would be able to use a
hardwired path, because the path is the same in many systems.

Maybe we could turn the configure option into enabling a lookup into
/usr/share/zoneinfo (hardwired). So if the files are there it uses
them. No need to set a symlink of any kind.

It would be even better to use --with-system-tzdata=/usr/share/zoneinfo
which enables lookup in the specified dir, hardwired at compile time in
the executable (I'm not aware if the patch already accepts a path
argument -- seems like the only sane choice). No symlink needed.
