The VFP registers are not currently included in coredumps,
and there's no existing note type where they can sensibly be
included, so this patch defines a dedicated note type for them.

This probably ought to go in include/elf.h, where all the
other NT_ types are defined ...

OK ... I was wondering since it's arch-specific.

But I can easily move it.
