Qt 4 changed the moc string table format following http://library.bagrintsev.me/CPP/dsohowto.pdf Section 2.4 and we have since added qOffsetStringTable to make applying this technique simpler.

I'm attaching Drepper's relinfo.pl script for progress reporting.
And here's a shell script to find where relocs originate: https://stackoverflow.com/a/19338343/134841
