I was going to type, "That can't be true!  Both sections are identical,
so that commit *couldn't* have done it!"

Being the careful sort, look closer.  Look closer.  Then realize if one
reads fast they look identical, but they're getting *slightly* different
values for ${XEN_TARGET_ARCH}.  Mainly for $(make_args_xen),
${XEN_TARGET_ARCH} gets $(xen_arch_$(flavour)), but for
$(make_args_tools), ${XEN_TARGET_ARCH} gets $(xen_arch_$(DEB_HOST_ARCH)).

Three of us and we didn't spot that difference.  Should still combine
${XEN_COMPILE_ARCH} which remains identical for both values.
