[PATCH 2/4] clang: Enable cmake flags for llvm, clang, lld tests

[Deepesh.Varatharajan@windriver.com]

From: Deepesh Varatharajan <Deepesh.Varatharajan@windriver.com>

Enable the necessary CMake flags to build and run tests
for LLVM, Clang and LLD. Install the LLVM target tools
needed to run tests via llvm-lit inside QEMU.
