[yocto] Raspberry Pi 3 build issue

[alexis.lothore at gmail.com]

Hello Paul,
thanks for the try. It should means that there is a detail on my setup 
which prevents the build from being done. I encounter the error on the 
commits id your provided too. I also tried being on last tag on poky 
project for morty branch, without success. I also suspected my python 
configuration/version so I resintalled it completely, but It made no 
change to the error.
