Link stage of libip6t_NETMAP failed since recently.
CCLD libip6t_NETMAP.so
/usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld:
cannot find -lip6tc
libip6t_NETMAP.c uses the "ipv6_prefix_length" function from
libip6tc.so; "-lip6tc" is used in the Makefile, but, the directory to
it is not specified.
Why does the link succeed for some people? Because
/usr/lib(64)/libip6tc.so satisfies -lip6tc, but not all environments,
especially those without iptables development files, have that file,
hence this link error can happen.
By suggestion of Mike Frysinger, this patch uses libtool to produce
and link the plugins.

Like this? We cannot really get rid of mentioning .libs without involving
libltdl, and there I really do not want to go.
If you ask me, we should just move ipv6_prefix_length into libxtables.
