I've built most of the base repository of Arch Linux on my RPi4 without cross compiling. I'm buying a few more so that I can go 'full Gentoo' and pretty much rebuild the world.
Have a recording of a container booting from a rebuilt userland:

It might feel like the ARM packages are somehow special but really only the blobby bits like the RPi firmware is. Everything else is just your bog standard armv7/aarch64 ELF.
So yeah, back up a GCC binary or bootstrap, I guess? I can probably email you a tmux binary in a pinch, plus I have a full local mirror of the repo for the apocalypse? :P
