Rollup merge of rust-lang#140357 - onur-ozkan:133840, r=clubby789

bypass linker configuration and cross target check on `x check`

I was going to handle this using the untracked env approach, but I realized it somehow doesn't regress rust-lang#130108 anymore...

Anyway, if it works, it works. 😄 No need to dig deeper but my guess is we moved some cache-invalidating env from these functions to others.

Fixes rust-lang#133840
