Somehow, CCACHE does not work for me, which has an error message like missing 'malloc/malloc.h'. I used the following scripts without CCACHE.

  $ cat build_llvm_debug.sh
  cd llvm-project/llvm/build
  
  #    -DLLVM_CCACHE_BUILD=ON \
  #    -C llvm-project/clang/cmake/caches/BOLT-PGO.cmake
  #    -DBOOTSTRAP_LLVM_CCACHE_BUILD=ON \
  
  cmake .. \
      -DLLVM_APPEND_VC_REV=OFF \
      -DLLVM_ENABLE_LLD=ON \
      -DBOOTSTRAP_LLVM_ENABLE_LLD=ON \
      -DBOOTSTRAP_BOOTSTRAP_LLVM_ENABLE_LLD=ON \
      -DPGO_INSTRUMENT_LTO=Thin \
      -DLLVM_ENABLE_PROJECTS="clang;lld;bolt;llvm" \
      -DCMAKE_BUILD_TYPE=Release \
      -DLLVM_ENABLE_ASSERTIONS=ON \
      -DLLVM_LIT_ARGS="-v -vv" \
      -G Ninja \
      -DCMAKE_INSTALL_PREFIX=$PWD/install
  
  ninja && ninja install

It works fine with me,

Does CCACHE impact the build? If you can help me resolve CCACHE build issue, I am happy to try the build again.
