Auto merge of rust-lang#130135 - Kobzol:bootstrap-check-linker, r=onur-ozkan

Do not skip linker configuration for `check` builds

This essentially reverts a part of rust-lang#128871, to fix rust-lang#130108. This is mostly a hotfix until we can figure out a better way to both avoid rebuilds and avoid configuring the linker for `x check`.

Skipping linker for check builds was causing unexpected rebuilds.

Fixes: rust-lang#130108
