Add sys-apps/star to your list.

The only problem I see with this are concurrent emerge processes (not 
supported now, but hopefully in a future Portage version). Apart from that it 
is a bit ugly to have this code in every affected ebuild, so maybe using a 
CHECK_SYMLINK="${ROOT}/bin/tar" variable and having the rest of the code in 
an eclass would be a good idea.
