Log:
  MFC r234772:
    Import stdbuf(1) and the shared library it relies on.
    This tool changes the default buffering behaviour of standard
    stdio streams.
  
    It only works on dynamic binaries.  To make it work for static
    ones it would require cluttering stdio because there no single
    entry point.
