make_standalone_toolchain: OBSOLETE

% ~/Library/Android/sdk/ndk/29.0.14206865/build/tools/make_standalone_toolchain.py 
THIS TOOL IS OBSOLETE. The $NDK/toolchains/llvm/prebuilt/darwin-x86_64/bin directory contains
target-specific scripts that perform the same task. For example,
instead of:

    $ python $NDK/build/tools/make_standalone_toolchain.py \
        --arch arm64 --api 21 --install-dir toolchain
    $ toolchain/bin/clang++ src.cpp

Instead use:

    $ $NDK/toolchains/llvm/prebuilt/darwin-x86_64/bin/aarch64-linux-android21-clang++ src.cpp

See https://developer.android.com/ndk/guides/other_build_systems for more
details.

the following arguments are required: --arch
