Hmf... some of these seem to be outright omissions (pivot_root() and
umount2() especially), and probably indicate bugs or that the stock
kernel isn't up to date anymore.

I can see umount() being missing (as in "use umount2()"). time() I
guess can be emulated with gettimeofday(), but select() being missing is
rather odd (is this a "emulate using poll()" philosophy? Barf...)

If the maintainers of the above ports could give me a pointer to how the
above system calls are expected to be done I'd appreciate it. I'll
probably look through the glibc sources for hints in the meantime.
