26b9a2f4a1a53e6763aa83590aad0fce5013a458 changes Zig 0.10 to build the compiler (notably *not* its outputs, at least not by default) with its baseline CPU target, but we should ideally do it for both versions to increase reproducibility, as well as increase the number of users who are able to use Hydra-provided Zig binaries. This also adds a comment above the flag in 0.10, to explain why we're adding the flag, as we do with the RPATH one. See https://github.com/NixOS/nixpkgs/issues/214356 and https://github.com/NixOS/nixpkgs/issues/185665 for further context.
