    build: fix list-old-dirs / check-old-dirs
    
    Fix list-old-dirs to not generate empty line at the end of the
    output if OLD_DIRS happens to have a space at the end of the
    last word of the output before the final \n. Then that space
    is turned into \n and we end up with a blank line.
    
    Futhermore this gets converted into a "/" i.e. root fs when
    calling check-old-dirs.
    
    This is the regression since a8267ecc3df0a.
