https://github.com/shlomif/fortune-mod/pull/69

The intention of LOCALDIR seems to be to allow local cookies to be
provided by the sysadmin in e.g. /usr/local/share/fortune,
but if set, before this patch, even cookies distributed
by upstream were stored there (and nothing in COOKIEDIR, e.g.
/usr/share/fortune - https://bugs.gentoo.org/865809).

Originally, we were setting LOCALDIR=COOKIEDIR=/usr/share/fortune to
workaround the issue, but see https://bugs.gentoo.org/857246.
