Then don't override it, wrap it in a function instead. This is
semantically clearer (if you give it a good name) and has the advantage
that it's clear what's going on. Iterating over a list of targets to
modify properties in a possibly distant part of the build system isn't
very transparent IMHO.

That's not to say I wouldn't like to have a way of obtaining a list of
targets defined so far...
