So this gets more interesting all the time.  I ran my tar through
strace, and it also opens CWD.  Running tar manually

    $ LD_PRELOAD=target/tools/root/usr/lib/librestrict.so 
target/tools/root/usr/bin/tar -C ~/tmp/x -p -xzf 
target/tools/packages/make-3.81.tools.gup
    /home/janneke/vc/gub/target/tools/root/usr/bin/tar: tried to open () file 
/home/janneke/vc/gub/.
    allowed:
      /home/janneke/vc/gub/target
      /tmp
      /dev/null
    Afgebroken (core dumped)

fails.  I'm attaching a patch that you can try as workaround.  Now it
puzzles me why tar does *not* fail in GUB for me.  It should.  Hmm.

Jan.
