Good point - there can be more than one branch types. I didn't know the code well when I created this patch.

If I choose 0x2000000 for ppc64le thunk section spacing (I tried several number slightly smaller than 0x2000000; they have no differences), `ThunkSections.size()` is at most 22. I'll abandon this.
