clang-cross: symlink cross versions of lto tools

llvm-ar llvm-ranlib and llvm-nm are often used during LTO
if enabled. These tools are currently not being found and
some build systems e.g. cmake disables them which then affects
-flto with clang. Enabling cross versions of them makes sure
they get detected properly during cross compile
