The problem is that you don't have modules (CONFIG_MODULES=y) support
enabled in your kernel, as the sunxi_defconfig in the kernel until very
recently didn't enable that - But it is naturally needed to build the
xtables-addons modules.
Arguably Buildroot should automatically enable this for you when
enabling the xtables-addons package, similar to how it is done for the
netfilter options even though it is quite a "big" option to enable
behind your back. Alternatively we could simply error out with a
sensible message like it was recently done for the pkg-kernel-module
infrastructure.

You most likely have modules support in your x86-64 kernel.
