this makes it much easier to understand test failures.
before:
```

5 clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
after:
```

```
this also fixes a failure related to missing whitespace; we don't actually care about whitespace in this test.
this avoids warnings from macOS ld

There was only ever one test which used this flag, and it was removed in rust-lang#132244. I think this is a bad flag that should never have been added; comparing by subset makes the test failures extremely hard to debug. Any test that needs complicated output filtering like this should just use run-make instead. Note that this does not remove the underlying comparison code, because it's still used if `runner` is set. I don't quite understand what's going on there, but since we still test on other platforms and in CI that the full output is accurate, I think it will be easier to debug than a test that uses compare-by-subset unconditionally.

separated out from #119286; this doesn't have anything user-facing, i just want to land these changes so i can stop rebasing them.
