[poky] [PATCH 2/4] flex-native: create a wrapper script for sstate installation

[Kevin Tian]

flex-native encodes M4 staging path in its binary, which breaks sstate
installation in a new build environment. Use create_wrapper to create
a wrapper script which explicitly set M4 environmental variable to the
new path
