On some older systems, such as SUSE 11, the compiling error shows
as:
.../dpdk/drivers/net/virtio/virtio_user/virtio_user_dev.c:67:22:
error: ?O_CLOEXEC? undeclared (first use in this function)
The fix is to use EFD_CLOEXEC, which is defined in sys/eventfd.h,
instead of O_CLOEXEC which needs _GNU_SOURCE defined on some old
systems.
