Add support for non-Intel architectures

I have a CLI tool that installs different binaries depending on the system architecture, and it worked fine so far for Windows, macOS and Intel GNU/Linux, but when I tried it on a Raspberry Pi, it installed the x86 binary, which obviously is not the desired effect.

Since Node.js is available on non-Intel architectures too, it would be recommended to support them too, and by all means avoid converting from one architecture to another.
