OMFG, you just gave me another reason to hate on this rust-bucket of a
language :-/ What language can't even build an old version of its own
runtime :-(

Anyway, given this core nonsense is now CFI unsound, it is no longer
suitable to build the kernel. So either refrain from using part of the
core that trips this, or get it fixed asap.
