The problem is that iptables-xml links against libxtables.la, and we never
build a version of libxtables.la that has -DNO_SHARED_LIBS=1. This isn't
a problem for iptables-static because we build xtables.c separately for it,
rather than linking against libxtables.la.
Also we can't just add -DNO_SHARED_LIBS=1 to the cflags for libxtables.la
because that would break when both --enable-static and --enable-shared
are specified.
