Sorry, this had dropped out the end of my email queue.

Yes, at least from the description it looks like .opd has the same
problems as .eh_frame. So basically:

* Add a OpdInputSection.
* Add a OpdOutputSection.
* In OpdOutpuSection::addSection, parse the .opd section, ignoring
entries that point to discarded (comdat or gced) section.

Cheers,
Rafael
