errno not being thread local makes it almost entirely useless for anything
at all. I don't typically make use of it
in Nut, but if I did I'd have tried to move it to the thread structure and
turn errno into a macro that referenced that.
In most cases of errors I can't come up with a recovery strategy that errno
could be used for, so it's not that great
outside of testing or other instances where there's human interaction or a
log to report it to.
