We want to use the local kernel headers, but -I../../include/uapi leads us into
a world of hurt. Instead we create a dummy include/ dir with symlinks.
If we just use #include "../../include/uapi/linux/virtio_blk.h" we get:
../../include/uapi/linux/virtio_blk.h:31:32: fatal error: linux/virtio_types.h: No such file or directory
#include <linux/virtio_types.h>

# This creates the demonstration utility "lguest" which runs a Linux guest.
