The overlay is not a proper overlay

One of the usescases for overlays is using nixpkgs' splicing for cross-compilation. However, as the overlay exports a static package that doesn't use final.callPackage from overlays, the splicing is lost.

This derivation produced the following outputs:

Note that I don't plan to use this (in fact I haven't even started my Zig journey), but just wanted to inform about this nix thing
