miri no longer builds after rust-lang/rust#81718

[rust-highfive]

Hello, this is your friendly neighborhood mergebot.
After merging PR #81718, I observed that the tool miri has failing tests.
A follow-up PR to the repository https://github.com/rust-lang/miri is needed to fix the fallout.

cc @m-ou-se, do you think you would have time to do the follow-up work?
If so, that would be great!

Hey @rust-highfive, don't blame the messenger rollerupperer!

Looks like this was #80394 :)
