Inconsistent use of `ld-options`

**Describe the bug**

I like having these in my cabal config to suppress some warnings:
```
gcc-options: -Wl,--allow-multiple-definition
ld-options: -Wl,--allow-multiple-definition
```

This produces (silenced by default) errors on cabal build:
```
$ cabal build -v3 | grep allow
...
Running: "C:\ghcup\ghc\9.6.6\lib\../mingw/bin\ld.lld.exe" "--help" "-Wl,--allow-multiple-definition"
lld: error: unknown argument: -Wl,--allow-multiple-definition
...
➜ $(cygpath -m 'C:\ghcup\ghc\9.6.6\lib\../mingw/bin\ld.lld.exe') --help | grep allow
--allow-multiple-definition
...
```

The output seems to indicate we should remove the `-Wl,` from `ld-options`. However, if done so we get a different error in another command:
```
➜ cabal repl -v3 | grep -v "with environment"
...

Notice how ld-options are passed as `-optl` flags to GHC which gives them to `clang`, but previously we were passing them to `lld` ourselves.

For my case this is not particularly important because the `lld` errors in the first case won't change depending on this flag, as my `lld` does not support `-x` but for users whose `lld` does support `-x`, if they specify `ld-options` with `-Wl`, the command will fail and Cabal will think that `-x` is not supported.
