Yes, runtime it definitely won't work. But since the LXC code was
already planning on being able to build on systems not providing those
syscalls, I was staying in line with this decision.

But I agree with you, it's probably better to keep the >= 3.0 headers
dependency. However, the comment that the dependency comes from libcap
should be changed.

Should I change a patch to fix this?
