Hm, this looks like an LLVM issue. What is strange to me is that the target seems to be x86_64-unknown-linux-gnu based on your logs. The target should actually be something to do with bpf instead.

I'm currently quite busy for the rest of this week, but I'd be happy to help figure this out next week.
