Hmm, it looks like this will be a bit tricky for future
rationalization; looking at FreeBSD's elf.h I see they diverge after

#define AT_EXECPATH     15      /* Path to the executable. */
#define AT_CANARY       16      /* Canary for SSP. */
#define AT_CANARYLEN    17      /* Length of the canary. */
#define AT_OSRELDATE    18      /* OSRELDATE. */
#define AT_NCPUS        19      /* Number of CPUs. */
#define AT_PAGESIZES    20      /* Pagesizes. */
#define AT_PAGESIZESLEN 21      /* Number of pagesizes. */
#define AT_TIMEKEEP     22      /* Pointer to timehands. */
#define AT_STACKPROT    23      /* Initial stack protection. */

#define AT_COUNT        24      /* Count of defined aux entry types. */

However there is already a conflict, so I have no objection to this
addition.  I'll probably submit an #ifdef patch in the short term for
the FreeBSD values, but will have to ponder Linux-FreeBSD or
FreeBSD-Linux cross debugging later.
