This resolves compiler warning:

extensions/libext_srcs/gen/gensrcs/external/iptables/extensions/libxt_addrtype.c:263:14: error: implicit declaration of function 'ffs' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
  int first = ffs(val);
              ^

Test: builds with less warnings
