[llvm-dev] Install clang+llvm-9.0.1-aarch64-linux-gnu.tar.xz

[Q-engineering via llvm-dev]

Dear Members,

In order to get TensorFlow 2.7 working I need to install libclang 9.0.1 
on my aarch64 RPi.
There is no clang version 9 repository for Debian 10.
Install from scratch is possible, but requires a huge amount of memory 
and is very time consuming.
Installation of the pre-built binaries 
(clang+llvm-9.0.1-aarch64-linux-gnu.tar.xz) look the best option here.
But how to install them on a Raspberry Pi 64-OS?

Any help appreciated!
