FWIW, I finished rebuilding world w/ 17.0 over the weekend, and it
looks like my third-party binaries all work the same as they did
before.  That's what I expected based on my understanding of the PIE
change: it didn't change the ABI or the way dynamic library linkage
worked.

I did have to grab the qtwebkit:4 ebuild out of the attic, but that's
apparently still working too.
