    phase1: handle source directory with libc suffix
    
    The ARC architectures use "generic-uClibc" instead of the expected "generic"
    as subtarget directory name, leading to errors in the rsync step because the
    expected directory cannot be found.
    
    Extract the libc flavor from the generated .config and decide whether to use
    a directory suffix based on the value obtained in order to let ARC uploads
    complete successfully.
