skb_linearize is controlled by ./linux/include/openswan/ipsec_kversion.h:

#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,18)
#define HAVE_NEW_SKB_LINEARIZE
#endif

I do notice that the XEN check, which also changes this, is missing, so
try adding just below there:

/* this is the best we can do to detect XEN, which makes
 * patches to linux/skbuff.h, making it look like 2.6.18 version
 */
#ifdef CONFIG_XEN
#define HAVE_NEW_SKB_LINEARIZE
#endif
