Attempt to allow Building of armhf and aarch64

[sithlord48]

Add armhf and aarch64 to the list of build-able architectures
Todo : Replace container build with a proper docker setup

This will be required for linuxdeploy/linuxdeploy#189
Works until it fails to pull linuxdeploy-arch from github for armhf and aarch64

Hey guys. Any updates on this? I'm not trying to push, but I was almost about to create a new ticket to request adding support for ARM64 (aarch64) binaries, ready for download in the release page, as I am working on Linux ARM64 on a daily basis. I keep getting thrown back from time to time due to lag of support of some little software projects that I'd like to give some more attention to however :)

I'm not a fan of third-party actions, however that could be solved. I wonder, though, if this really not-so-complex tool couldn't just be cross-compiled on Ubuntu with clang or g++-aarch64-linux-gnu?

Anyway, the main issue I have with this PR is the use of that third-party action. In my opinion, CI should always be written in a way so the majority can be run locally (and on virtually any CI system). The actions code should be limited to the minimum required to run all required configurations.

Edit: I'll have a closer look later.
