Edmund, thanks for pointing out the exact cause of the FTBFS.

The issue has been fixed with libuv commit 1d8332f, which takes
a slightly different approach by calling either uv__epoll_wait
or uv__epoll_pwait, depending on availability [1].

This bug would have been avoided if Julia had not forked libuv
without keeping it up to date :-(. I will forward the issue to
the Julia maintainers and hopefully motivate them to switch to
upstream libuv sooner than later.

Regards,
Peter
