It won't be used anymore.

cd ${ANDROID_NDK_HOME}/build/tools
    INSTALL_PATH=/tmp/llvm/prebuilt/"$(echo $(uname -s)-$(uname -m) | tr '[:upper:]' '[:lower:]')"
    ./make_standalone_toolchain.py --arch=arm64 --api=27 --stl=libc++ --install-dir=${INSTALL_PATH} --force
cd ${INSTALL_PATH}
    tree -L 2 ./lib64/clang/9.0.0/lib

The build step uses Gradle 7.2.0+. If you don't know how to use it, latest Android Studio can do the work.

$ git clone https://github.com/luncliff/Muffin
$ cd ./Muffin
$ gradle clean assemble
