## We create initial ThunkSection before the gap. Because the ThunkSection
## selection code isn't so precise, we may create an unused thunk there (0x10704).
## In the next pass we will create a ThunkSection after the gap. There used to be
## a bug reusing the first ThunkSection (unreachable) due to the large r_addend.
