Hi, the `libgo` under gollvm seems is a part of gollvm, and after I delete it there's another error: ``` $ cmake -DCMAKE_BUILD_TYPE=Debug -DLLVM_USE_LINKER=gold -G Ninja ../llvm-project/llvm -- Native target architecture is X86 -- Threads enabled. ... -- Targeting XCore -- default linker set to "gold" CMake Error at tools/gollvm/CMakeLists.txt:131 (add_subdirectory): add_subdirectory given source "libgo" which is not an existing directory.
