The motivation behind this is to alleviate the problem described in https://github.com/NixOS/nixpkgs/issues/41340. I'm not sure if this completely fixes the problem, but it eliminates one more area where we can exceed command line length limits. This is essentially the same change as in #112449, except for `ld-wrapper.sh` instead of `cc-wrapper.sh`. However, that change alone was not enough; on macOS the `ld` provided by `darwin.cctools` fails if you use process substitution to generate the response file, so I put up a PR to fix that: https://github.com/tpoechtrager/cctools-port/pull/131 … and I included a patch referencing that fix so that the new `ld-wrapper` still works on macOS.
