To bootstrap clang/LLVM with ThinLTO, follow these steps:
``CMAKE_EXE_LINKER_FLAGS:STRING=``. Note the configure may fail if
linker plugin options are instead specified directly in the previous step.
+The `BOOTSTRAP_LLVM_ENABLE_LTO=Thin`` will enable ThinLTO for stage 2 and
+stage 3 in case the compiler used for stage 1 does not support the ThinLTO
+option.
