[Build error] using llvm-18 toolchain build compiler get lld error

[zhoujingya]

How to reproduce

First, download llvm-18(maybe higher version too), then use clang-18/clang++-18 as c/cxx compiler

# Build llvm
build_llvm() {
  if [ ! -d "${VENTUS_BUILD_DIR}" ]; then
    mkdir ${VENTUS_BUILD_DIR}
  fi
  cd ${VENTUS_BUILD_DIR}
  cmake -G Ninja -B ${VENTUS_BUILD_DIR} ${DIR}/llvm \
    -DLLVM_CCACHE_BUILD=ON \
    -DCMAKE_C_COMPILER=clang \        <-----------
    -DCMAKE_CXX_COMPILER=clang++ \ <-----------
    -DCMAKE_LINKER=mold \
    -DLLVM_OPTIMIZED_TABLEGEN=ON \
    -DLLVM_PARALLEL_LINK_JOBS=12 \
    -DCMAKE_BUILD_TYPE=${BUILD_TYPE} \
    -DLLVM_ENABLE_PROJECTS="clang;lld;libclc" \
    -DLLVM_TARGETS_TO_BUILD="AMDGPU;X86;RISCV" \
    -DLLVM_TARGET_ARCH=riscv32 \
    -DBUILD_SHARED_LIBS=ON \
    -DLLVM_BUILD_LLVM_DYLIB=ON \
    -DCMAKE_INSTALL_PREFIX=${VENTUS_INSTALL_PREFIX}
  ninja
  ninja install
}
