It is a QoI issue, it wouldn't be hard to add something for all of these
machines.
I would like to make it mandatory that all machines implement
ABORT_INSTRUCTION, but haven't suggested it yet.
It's the only way in which glibc aborts in situations where a function call
can't be made or error conditions have forced us into a fallback e.g.
check_one_fd, abort, _exit.
