The illumos linker does not support --strip-debug

When building and testing rust 1.64.0 on illumos, we saw a large number of failing tests associated with:

```
   = note: ld: fatal: unrecognized option '--strip-debug'
           ld: fatal: use the -z help option for usage information
           collect2: error: ld returned 1 exit status
```

The illumos linker does not support the `--strip-debug` option (although it does support `--strip-all`).
