python3: propagate overrides of spliced pythons (#498251)

        );

      }

      // __splices;

      # When we override the interpreter we also need to override the spliced

      # versions of the interpreter. NOTE: In lua-5/interpreter.nix, this

      # filter is different - we take every attribute from @inputs, besides

      # derivations. That filter causes cross compilations issues for Python

      # See e.g:

      #

      # pkgsCross.armv7l-hf-multiplatform.buildPackages.python3Packages.bcrypt

      #

      # And the following Nixpkgs issues/PRs:

      #

      # - https://github.com/NixOS/nixpkgs/issues/48046

      # - https://github.com/NixOS/nixpkgs/pull/480005 (Wrong PR)

      # - https://github.com/NixOS/nixpkgs/pull/482866 (Correct fix)

      # - https://github.com/NixOS/nixpkgs/pull/498251 (Re-adds this @inputs filter)
