When switching from master branch to 19.07 or older, we need to ensure that Python symlink in staging bin directory points to Python 2. We can't rely completly just on SetupHostCommand as its executed only in cases when the $(STAGING_DIR_HOST)/bin/python doesn't already exist, so we need to remove it before running SetupHostCommand. This is a cherry-pick of3b68fb57c9with python3 instead of python2 Signed-off-by: Petr Štetiar <ynezz@true.cz> Signed-off-by: Etienne Champetier <champetier.etienne@gmail.com> (cherry picked from commit799de7c641)
