Auto merge of #120803 - onur-ozkan:fix-compilation-cache, r=Mark-Simulacrum

always run `configure_linker` except for mir-opt tests

`configure_linker` now runs consistently unless it's for mir-opt tests. Previously `!= "check"` condition was causing dirt in the cargo cache between runs of `x anything-but-not-check` and `x check`.

 Fixes #120768
