Only copy, rename and link `llvm-objcopy` if llvm tools are enabled Fixes rust-lang#132719. cc `@bjorn3` who reported the bootstrapping problem for cg_clif. cc `@davidtwco` in case this might be problematic for linux -> macOS cross-compile builds, but seems very unlikely. cc `@albertlarsan68` (co-reviewed rust-lang#131405) r? bootstrap
