    Run installation commands as shell jobs
    
    This greatly speeds up installation time on multi-core systems:
    for example on my machine from 4 minutes to 1 minute.
    
    Yocto project has been carrying this patch for several years,
    it's been tested on all kinds of build hosts under all kinds of
    system loads, so it's completely robust.
