In reply to @outfoxxed:outfoxxed.me
the package just uses ${libstemmer} directly, and not via a native/target dep
how is that suppposed to be handled?

Splicing can't work when packages do that.

Use targetPackages.libstemmer instead and it might work.
If you don't want to patch Nixpkgs, you can override { inherit (self.targetPackages) libstemmer; } instead.

In reply to @outfoxxed:outfoxxed.me
Since this is in the critical chain to even getting a zero package nixos install running I'd assume theres some reason everyone doesn't run into this

Have you looked at why it's in the build time closure?

Changes to other packages may have resulted in it being required where it wasn't before.
I suspect that one of the dependants in the chain can be overridden to not require it.

libstemmer = builtins.trace "${targetPackages.libstemmer} ${buildPackages.libstemmer} ${pkgs.libstemmer}" targetPackages.libstemmer;

prints 3x and only in one of them is targetPackages set correctly
