If your Linux system has NETLINK support, then you don't need
SIOCGIFCONF. All Linux kernels should have NETLINK, but you can
double-check that inside the top-level config.h you have:

/* Define to 1 if you have the <linux/rtnetlink.h> header file. */
#define HAVE_LINUX_RTNETLINK_H 1

/* Define to 1 if you have Linux-style netlink sockets (AF_NETLINK) */
#define HAVE_NETLINK_SOCKETS 1

About the above AWK error, I am surprised that you see it only in
the static_routes directory, but you didn't see it in other
directories (fea, fib2mrib, etc).
Can you try to run the same command by hand:

cd static_routes
../utils/xrl_wrappers_generator.sh ../xrl/targets/static_routes.xrls >
../static_routes/xrl_static_routes_shell_funcs.sh

For comparison purpose, you can run some of the other commands that
presumably succeeded:

cd ../fib2mrib
../utils/xrl_wrappers_generator.sh ../xrl/targets/fib2mrib.xrls >
../fib2mrib/xrl_fib2mrib_shell_funcs.sh

If the command constantly fails inside the static_routes directory,
a quick work-around would be to just put a dummy empty file instead
of static_routes/xrl_static_routes_shell_funcs.sh and continue with
the compilation:

touch static_routes/xrl_static_routes_shell_funcs.sh

You can get away with this, because currently the above file is not
really used.
