This seems to be a very nice piece of work!  Congrats, Jakub!

I'm wondering whether you already support something like `take these
libraries into account, but don't change them'.  This would be nice to
do incremental prelinking against system libraries, but still as a
regular user, for example, right after building a bunch of new
libraries and in preparation to replacing them in the system.
