    rootfs-postcommands: add test for unsatisfied RRECOMMENDS
    
    The do_rootfs log contains a number of unsatisfied package
    recommendations. At the moment those are only visible when
    reviewing the rootfs log.
    
    This patch adds an extra check to surface any unsatisfied
    recommendation  as WARNINGS to the build output.
    
    Enable this check with:
    ROOTFS_POSTPROCESS_COMMAND += "rootfs_log_check_recommends;"
    
    (From OE-Core rev: 9d049bf7941f30e35c51775684559e95185fba96)
