It is intended here, such that the register sets are actually used by
linux_nat_collect_thread_registers and get_core_register_section.

If I didn't miss anything, M68K and IA64 were the only Linux targets
without regset_from_core_section gdbarch methods before.  After the
patch series all Linux targets should have them, and all their regsets
should have supply- *and* collect methods.
