llvm: use llvm-tools instead of lld to provide binutils & use hardlink instead of copy (#31005)
* llvm: use llvm-tools instead of lld to provide binutils
lld only contain ld, while llvm-tools contain most other stuff (ar, nm, objdump, ranlib, windres, etc.), so it's more like an replacement of binutils.
Add lld to llvm-tools' depends, so that it also provides ld
* cleanup
* use hardlink instead of copy
