I made this change for 8C46.plist, 8B15.plist, 8A428.plist, and  
7W98.plist.

After discussion with Shantonu on IRC, I've committed some changes  
which differ from the above description.  `darwinxref binary_sites`  
continues to use the standard "look in the project, then in the  
build" approach.  If there is an HTTP error on all of the URLs  
provided, then darwinbuild will request the binary_sites of the  
inherited build, and so on.

I have already made these compatibility symlinks.
