    Makefile: copy symbolic links when creating lab-data archive
    
    This way, we can have symbolic links in the sources,
    to share files between several lab variants (such as
    "embedded-linux", "embedded-linux-bbb" and "embedded-linux-qemu").
    
    That's better than keeping multiple copies of the same file
    in the sources, which may go out-of-sync if a contributor
    doesn't notice they are supposed to be the same.
    
    Tested on the embedded-linux-bbb-labs.tar.xz archive.
