found crate cfg_if compiled by an incompatible version of rustc

[pickfire]

I think this is more of a rust issue rather than cfg-if issue so just reporting it here. I was building cfg-if using stable compiler, I might have built it with nightly compiler in the past. Feel free to close this (since I don't think it is actionable), I did send this to rust rust-lang/rust#86551. Note that cargo b works but only cargo c does not work.

Closing this, not really the crate issue, I found it also happens to other crate.
