cmd/link/internal/ld: clean tmpdir obj timestamps This patch changes the Go linker to "clean" (reset to Unix epoch) the timestamps on object files copied to the tmpdir that is presented to the external linker or archive tool. The intent is to improve build reproducibility on Darwin, where later versions of xcode seem to want to incorporate object file timestamps into the hash used for the final build ID (which precludes the possibility of having reproducible Go builds). Credit for this idea goes to Cherry (see https://github.com/golang/go/issues/64947#issuecomment-1887667189). Updates #64947.
