Yes, if we always applied relocations in .opd first, then we'd be able to save and use that information later for the relocations in the text sections.

Should we add some kind of target hook that allows it to somehow adjust the order in which the relocations are applied? Does this require separating that process from the order in which the sections are written? In short, how would you like this to work?
