    kernel-yocto: propagate configuration errors to bbclass
    
    As pointed out by klapperichpaul johndeere com, missing configuration
    fragments were being picked up twice, once by the tools and once by the
    bbclass. Unfortunately, the tools error message was being detected as
    configs, and hence no error was reported at all.
    
    Rather than catching the output of the tools, we can instead check the
    return code and propagate the error message from the tools directly to
    the user.
