Fix a configure error when the IPFILTER option is selected. An example

of the error is:

checking for struct natlookup.nl_inipaddr.in6... no
checking for struct natlookup.nl_realipaddr.in6... eval: ${+...}: Bad substitution
===>  Script "configure" failed unexpectedly.
Please report the problem to timp87@gmail.com [maintainer] and attach the
"/export/wrkdir/amd64/export/home/cy/freebsd/git/ports/www/squid-devel/work/squid-4.0.25/config.log"
including the output of the failure of your make command. Also, it might be
a good idea to provide an overview of all packages installed on your system
(e.g. a /usr/local/sbin/pkg-static info -g -Ea).
