From: "mark.yang" <mark.yang@lge.com>

Currently, LLVMgold.so is not built because the binutils headers
are missing during the build process.

This allows LLVM to find the necessary headers and build the LLVMgold.so,
which is required for Link Time Optimization (LTO) support properly.

changes in v2:
- Add llvm-linker-tools package to include LLVMgold.so and libLTO.so
