If I build flang with `-DFLANG_DEFAULT_LINKER=lld`, the system `ld` is used.
```
$ bin/flang-new -### t0.f90
flang-new version 18.0.0 (git@github.com:kkwli/llvm-project.git d2d29288bd4f64e0966db42b821d84587501669b)

```
However, if I use `-DCLANG_DEFAULT_LINKER=lld`, `ld.lld` is used.

If I build flang with
-DFLANG_DEFAULT_LINKER=lld, the systemldis used.However, if I use
-DCLANG_DEFAULT_LINKER=lld,ld.lldis used.
