Re: Fix stack backtraces on 26-bit ARM

I understood from BenH response and from a private conversation with
Andrew that it was OK to check this in, so I did it (although this is
a little borderline w.r.t. maintainership -- see below).

Note that this is rather a new target (although an ARM one) so we would
need a maintainer for it. You can see that it is basically new files
and I don't have a NetBSR ARM machine around here (nor does Scott, I guess).

I believe we would need to add the following to gdb/MAINTAINERS until
this is decided:
