A full build environment (the way I’m used to having it) comprises the end-to-end automation for creating a full build, triggered by an external code repository and (when possible) doing automated testing.

I understand that you might be used to manually bootstrap things, but I tend to go for fully reproducible builds and that usually requires a minimal degree of automation. I did that for my Inferno builds for the Pi (which, alas, are now lost) and do rely on Linux tools for building, because that’s what I can host in the public cloud (which is also what I do for work).

Fortunately, I have access to machines with nested virtualisation, so I might be able to get Plan9 running inside QEMU inside a modern Linux kernel with fair performance - but that does not preclude the need to automate things.
