Suggestion: duplicate this test, compile one copy with explicit -pie and
one with explicit -no-pie, and xfail the -pie version. That avoids
having testing depend on the configuration of the build toolchain, gets
us back to green buildbots quicker, and we can worry about fixing 16634
properly when someone actually has time to do that.
