Oops, I tried it only using a cross-compiler.  When I compiled
natively on ia64, it is still necessary to specify
LINUX_ARCH=ia64 on the make-line, else I get x86 configs.

I think the fix is to change in buildconfig/Rules.mk from

ifneq ($(ARCH),ia64)
  to
ifneq ($(XEN_TARGET_ARCH),ia64)

I'll roll this fix in at the next merge with xen-ia64-unstable.

Thanks,
Dan
