CI is broken: "LLVM ERROR: dwo only supported with ELF and Wasm"

[nicholasbishop]

CI started failing when nightly switched from 2022-08-25 (748038961) to 2022-08-26 (c07a8b4e0).

Error looks like this:

LLVM ERROR: dwo only supported with ELF and Wasm
error: could not compile `core`

See https://github.com/rust-osdev/uefi-rs/runs/8046893608?check_suite_focus=true for example.

Bisected and made a bug: rust-lang/rust#101071

[nicholasbishop]

I've put up a PR that should fix this issue: rust-lang/rust#101088

In the meantime, nightly-2022-08-25 can be used locally.

I think we're all good here now as of nightly-2022-08-31. Filed #498 to consider some sort of pinning in the future to avoid such a long CI outage.

Awesome, thanks for taking care of this!
