Arm build
Hi, guys. As talked in the gobetween telegram channel, I'm opening this Issue so we could add arm builds. I thing this is gonna be very helpful, for exemple, to running gobetween in Raspberry hardware.
Since there are a lot of options on how to build for ARM, what exactly do we need? https://github.com/golang/go/wiki/GoArm
I have built for Raspberry Pi 3B+ and it somewhat works. I have not gotten the config perfect but there doesn't seem to be any build-related issues. For now maybe it would help to have a sort of "install script" that builds and installs Gobetween and comes with source. You run the script and wait for it to build and then kaboom, it is ready. One thing that would be useful would be a thing that makes Gobetween controllable by the init system as a service. I believe snap allows this, but when building from source there is no such functionality. I made a startup script to start Gobetween on boot, haven't tested it yet. One last note on my installation, I got it to work but it is giving me an error now about not being able to elect a backend. Screenshot attached. Maybe the stuff in this post could be added, and if so, I can supply what I did to help. Things like scripts to install could just be added to source and also put into Go's version of a Makefile. I don't know how Go works so I cannot do that.
