-/* TODO:
- We should really create new local (static) symbols in destination
- object for each stub we create. We should also create local
- (static) symbols within the stubs when switching between ARM and
- Thumb code. This will ensure that the debugger and disassembler
- can present a better view of stubs.
-
- We can treat stubs like literal sections, and for the THUMB9 ones
- (short addressing range) we should be able to insert the stubs
- between sections. i.e. the simplest approach (since relocations
- are done on a section basis) is to dump the stubs at the end of
- processing a section. That way we can always try and minimise the
- offset to and from a stub. However, this does not map well onto
