    build: ensure silent Make behavior for json scripts
    
    Run the invocation of Make with verbosity in order to
    prevent the printing of Makefile level and subtarget status.
    e.g.  make[3] -C target/linux val.DEFAULT_PACKAGES val.ARCH_PACKAGES
    
    Remove piping of stderr, which is only useful when using
    the "communicate" method over the "run" method,
    and this script would not be written to handle a captured error anyway.
    
    For error testing, stdout and stderr can be set to a file object
    with the open() function like this:
    
    out = open('json_out', 'w')
    err = open('json_err', 'w')
    
    ...
    ...
    stdout=out,
    stderr=err,
