zig has a cross-compiler frontend (zig cc) which can be used as a drop-in replacement for a custom sysroot + binutils + gcc for several platforms. I've used it to build OCaml cross-compilers that only depend on zig itself (https://www.chrisarmstrong.dev/posts/ocaml-cross-compilation-an-experiment https://www.chrisarmstrong.dev/posts/ocaml-cross-compilation...). There are other projects that have used it in a similar way too.
