arm: make __rel_dyn_{start, end} compiler-generated
This change is only done where needed: some linker
scripts may contain relocation symbols yet remain
unchanged.
__rel_dyn_start and __rel_dyn_end each requires
its own output section; putting them in relocation
sections changes their flags and breaks relocation.
