I tried this locally, but it doesn't quite work:

```
>flang-new foo.f90
... fatal error LNK1276: invalid directive 'clang_rt.builtins-x86_64.lib' found; does not start with '/'
```

The directives appear in the object file with an extra space:

```
>flang-new -c foo.f90
>grep -ai defaultlib foo.o
 /DEFAULTLIB: clang_rt.builtins-x86_64.lib /DEFAULTLIB: libcmt /DEFAULTLIB: Fortran_main.static.lib /DEFAULTLIB: FortranRuntime.static.lib /DEFAULTLIB: FortranDecimal.static.lib.text
```

There should not be a space after `/DEFAULTLIB:` before the library name.
