iproute2/configure
Dan McGee 44e743e588 Make iproute2 configure script more flexible
On Arch Linux, we still install the iptables shared libraries in
/usr/lib/iptables/, even though the main library is installed to
/usr/lib/libxtables.so. This change checks all available locations to
correctly find the iptables library directory.
