Tensorflow build fix

[TomaszAIR]

tensorflow-lite on kirkstone-5.15.71-2.2.0 release seems to be broken, without additional, custom changes in bbappend the build hangs on following error

Provided changes helps with finding header files and compile the tensorflow-lite recipe.

Is there any chance that this will be reviewed? Should I assign someone?

Hi @TomaszAIR , I will have a look today.

Can you give me your setup steps so I can reproduce?

This appears to still be an issue with the kirkstone branch, just following the example here cause the same issue for me.
