Non-Docker / non-containerized build instructions

[UweSauter]

I learned about FireDBG a few days ago and I think that FireDBG could be a helpful tool. But as I am using Arch Linux and Rust 1.85 I suppose I need a new version of FireDBG.

As I don't have the intention to use Docker could you please release the required information to build FireDBG manually?
(I use systemd-nspawn for all of my containers.)

I see that a growing number of projects is hiding away that crucial information by providing containerized build solutions but I think that they harm themselves by doing so as the software is only built with a limited set of library versions and compiler versions. (The same is true for projects that release their software only inside a container…)

I tried to dissect the provided Docker files but fail at the latest when trying to find the build-tools directory that should contain the shell scripts for building.
