I have a patch which adds _fcntl for the ARM newlib port. It was even
approved, but, being the bad hacker-citizen that I am, it was never
committed.

However, I'll note that adding a dummy _fcntl (like in my patch) wasn't
one of your suggested fixes. I believe syscalls contains other dummy
implementations - so it seemed like the thing to do. What do you think?
Thanks,
