    reproducible_build_simple.bbclass: simple environment for reproducible binaries
    
    Export environmental variables needed for binary reproducibility with consistent values.
    
    This class can be used either directly via:
    INHERIT += "reproducible_build_simple"
    
    or can be inherited by a more complex/complete bbclass, for example a bblass which
    will crack SOURCE_DATE_EPOCH for each recipe.
