aarch64 support

[K2IE]

The configure script does not support aarch64 architecture.

$ sh autogen.sh

message when this script completes, then something went wrong and

You may now run ./configure in order to create a custom Makefile
that is suitable for your platform and environment.

download the most up to date version of the config scripts from

The problem here is the config.{guess,sub} from the GNU config project is too old to recognize your system (which I'm assuming is a Raspberry Pi?).

You can get newer config.{guess,sub} from GNU config project

Copy those two files into your spinhawk autoconf directory and rerun ./configure.

This suggestion does resolve the issue. I was able to build on a Raspberry Pi 4.
