Auto merge of #85953 - inquisitivecrystal:weak-linkat-in-fs-hardlink, r=joshtriplett
Fix linker error Currently, `fs::hard_link` determines whether platforms have `linkat` based on the OS, and uses `link` if they don't. However, this heuristic does not work well if a platform provides `linkat` on newer versions but not on older ones. On old MacOS, this currently causes a linking error. This commit fixes `fs::hard_link` by telling it to use `weak!` on macOS. This means that, on that operating system, we now check for `linkat` at runtime and use `link` if it is not available. Fixes #80804. `@rustbot` label T-libs-impl
