Thanks for catching both of these problems. Here is a new patch which
applies to xen-unstable. This builds successfully on x86, x86_64,
ia64-vp and ia64-non-vp.

Take a bite out of arch/ia64/xen-mkbuildtree-pre, which needs to go
away for inclusion of xen-ia64 in Fedora.
Converge the ia64-specific and general versions of
xen/drivers/Makefile and xen/drivers/core/Makefile. Use Kconfig
settings instead to control whether specific pieces are built. These
config settings might disappear when the ia64 p2m/vp conversion is
complete, but for the moment it's a clean way of handling the two
personalities of xen-ia64.
Handle evtchn/evtchn_ia64 with ifeq ($(ARCH),ia64) since this will go away with
the next pull of xen-ia64-unstable into xen-unstable, and I think this creates
less work to undo when that occurs.
