    STR:
- Download https://drive.google.com/file/d/1AESRw2pf8lbMwfKl4S238UlOBqf1YHCR/view?usp=sharing
- Unpack the archive and enter the `repro` directory.
- Run `lld-link @response.txt`

Expected result: success

Actual result:
```
lld-link: error: duplicate symbol: __declspec(dllimport) __load_timeBeginPeriod
lld-link: error: duplicate symbol: __declspec(dllimport) __load_timeEndPeriod
lld-link: error: duplicate symbol: __declspec(dllimport) __load_CoInitializeEx
lld-link: error: duplicate symbol: __declspec(dllimport) __load_GetClientRect
```

Removing `-DELAYLOAD:ole32.dll`, `-DELAYLOAD:user32.dll`, and `-DELAYLOAD:winmm.dll` from the response file makes the issue go away.

What's peculiar in this link is that there are COFF import files in gkrust.lib that repeats symbols from other `.lib`s. Those come from rust's raw-dylib feature. It somehow makes the linker trip with the delayload, but only on x86, not x86_64 or aarch64.
