Describe the problem

Since #234651 was merged, many derivation builders have been rebuilt using this excellent helper. This is great because it mostly unifies the API for builders, rather than the mostly ad-hoc mess before. This issue is for tracking the builders that are left.

This is for things that are shaped like so:

let
myBuilder = { arg1, arg2 }:
  stdenv.mkDerivation { inherit arg1 arg2; };
in
#...

Would also be nice to add documentation when these builders are modified as well :). Either inline so that the documentation shows up on Noogle, or docs in the docs directory for the Nixpkgs reference.

It is also generally recommended to move builders to their own separate file rather than having them inline, then just myBuilder = callPackage ./my-builder.nix { }.

Tracking
