I don't know what -single_module does, but this logic is entirely in
libtool. Furthermore, it's entirely in a darwin-specific section of
libtool. So, the best thing to do is try to find the darwin libtool
hero and see if they can give you some insight. Or, try slogging
through libtool.m4 and/or ltmain.sh and see if you can't figure out
what's happening yourself.
