A new profile has been added, called alpine-xen, that shoud be used
when trying to craft a Xen Dom0 LiveCD/USB.
Changes since v1:
* Removed dummy net setup, since xencommons doesn't need net to
start.
Please review and comment.

Nice!
In general, the Makefile is getting bigger and messier. We need to do
something to split it up. We should try avoid having profile specifics
in main Makefile and try avoid if/else in Makefile. (that is meant for
myself as well)

Have been thinking of other apkovls too, for for example
alpine-desktop. I am not convinced that shipping an iso with apkovl is
the prober direction to go though. We have talked about implementing
"policy" packages in apk so you could have a "profile" package for
different setups. policy pakcages could include some configuration that
could be overridden by user.
Not sure what the status for that is currently.

I think the helper funciton was pretty elegant :)

In case we go for shipping apkovls in iso's, we might want keep some
files in there too. So we should probably do that in subdirs.
hum... need to think about this.

I wonder if we could/should keep those in $(PROFILE).conf.mk...

... hmm.. maybe not. The xen structure is pretty different. Looks
difficult to put that in alpine-xen.conf.mk.
Also, we have the update-extlinux.conf tool. I think we should try fix
that tool so it could create isolinux.cfg suitable for iso image.

hard to do the above without special case for xen. hum...

I think I will apply this and we can think of how to clean it up later.
