Looks like we can't emulate x86_64-linux builds on aarch64-linux for all packages, like the treefmt-nix check,

treefmt-check> qemu-x86_64: QEMU internal SIGSEGV {code=MAPERR, addr=0x20}

Another instance when building neovim-ruby-env

This is just arm64 build (no emulation). So I don't know where qemu-x86_64 is coming into picture. :-/

Huh, why is it using x86 ruby as build dependency?

Because zyh6qa2nvjp9hnm0i1biv1lfzbixwmy8-neovim-ruby-env.drv is being built for that system

Oh, it is building the x86 configuration, because nixci (via devour-flake) will return all Linux systems,
