Compile and build for arm64-v8a

[yartaran]

I would like to build and run ML-EXAMPLES on HW arm64. I built the armnn according to the following document:

https://github.com/ARM-software/armnn/blob/branches/armnn_20_08/BuildGuideCrossCompilation.md

How to build ML-examples in order to run it on ARM HW ?

Thank you, Slava
