Thanks for the contribution! But how does this help, exactly? the bintools-wrapper should add the unwrapped derivation behind it to the path behind it, I believe.

When cross-compiling neither bintools is added directly to the path as far as I can see:

nix-shell /home/bnikolic/oss/nixpkgs -I /home/bnikolic/oss/  -A windows.mingw_w64 --arg crossSystem '(import <nixpkgs/lib>).systems.examples.mingwW64'                    
[nix-shell:~]$ env | grep binutils                                                                                                                                                                                 
                                                                                                                                                                                                               
[nix-shell:~]$                          

Instead they the GCC-wrapper symlinks to executables from binutils-wrapper (as far as I can understand things). Presumably this is why the assembler is already symlinked from the plain binutils to the wrapped version ?

Hmm the

addToSearchPath _PATH @bintools_bin@/bin

In bintools-wrapper's setup hook should be doing that.

Based on my experiments with #33167 it looks like this indeed isn't necessary, but haven't yet fixed all regressions so I'll keep it open until I know for sure, at least until #26805 lands.

@Ericson2314: now these PRs have been merged.

Good catch. It was indeed not needed, but I do want to take the exlanded listof programs to make env vars in bintool-wrapper's setup hook.
