I'm sorry for not getting back to you earlier. The log relevant to building LLVM itself is this (22M uncompressed):

[sys-devel:llvm-18.0.0_pre20231206:20231206-072428.log.gz](https://github.com/llvm/llvm-project/files/13627566/sys-devel.llvm-18.0.0_pre20231206.20231206-072428.log.gz)

I think the most relevant part is:

```

```

We don't install `LLVMDebuginfod.a` at all right now. I suppose I could try doing that but last we tried to do something similar, all hell broke loose because of its dependency on other libraries from LLVM. It's a mess, I'm afraid.

At this point, I think the only reasonable solution here is to include `LLVMDebuginfod` in `libLLVM`.
