This patch takes a bite out of xen-mkbuildtree-pre, which needs to
disappear eventually for inclusion of xen-ia64 in Fedora.  Probably
these config settings will 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.

This is sent to xen-devel because it's primarily common code that's
changing.

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.
