Thanks for mentioning this, I was going to ask "why don't we just abort
all the time". On non-embedded targets it could be useful to abort,
since it triggers the various distros error reporting tool (like ABRT on
Red Hat), and make reporting crashes easier. But the embedded target
case also makes sense. Your patch LGTM, it's a good change on its own.
If someone wants to add a --make-gdbserver-abort-on-internal-error
configure switch later (and convince distros to use it), I'd be ok with
that.
