Linux kernel has SO_REUSEPORT support since version 3.9. But it's not
configurable, it's always-on. See [1].
But kernel support is not enough, as SO_REUSEPORT should be mentioned in
kernel headers provided by linux-libc-dev (I'm assuming that you try to
build nginx from the source). Hence, per [2] - install linux-libc-dev
from the backports too.
