This should be a generic issue. from gcc/config/arm/arm-c.c:

  if (arm_arch_iwmmxt2)
    builtin_define ("__IWMMXT2__");
  /* ARMv6KZ was originally identified as the misspelled __ARM_ARCH_6ZK__.  To
     preserve the existing behavior, the misspelled feature macro must still be
     defined.  */
  if (arm_arch6kz)
    builtin_define ("__ARM_ARCH_6ZK__");

How about adding a "| tail -1" to the configure script (and reporting upstream)?
