[PATCH] portability: configure top level dependencies per architecture

[Christian Ehrhardt <ehrhardt-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>]

This includes the comments from Avi to "[PATCH] portability: add top level
config-$arch files v2". Putting the arch dependencies into if's saves us 4
config-$arch files which are not essential to fix the current issue.
Since this is copy&paste from Avis response to v2 I added him to the From list

changes to v2:
 - remove config-$arch files 
 - put arch dep in if's checking the arch to add more dependencies to a
   target directly in the top level Makefile

From: Christian Ehrhardt <ehrhardt-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>
From: Avi Kivity avi-atKUWr5tajBWk0Htik3J/w@public.gmane.org

This allows per arch configuration for the top level Makefile of
kvm-userspace e.g. allowing to disable extboot for non x86 or disabling
kvmctl build until ported to an architecture.
