This is now done. There is now a separate "minios-xen" opam package
(and mirage-xen-minios now just depends on that). You should now be
able to pin my minios-xen Git repository to test the latest version,
just as for any other library, e.g.

Â opam pin add minios-xen https://github.com/talex5/mini-os.git

As part of this, I've also made a new Mini-OS release (0.7):

* First release from the separate Mini-OS repository
* x86: Don't print a stack trace on exit
* printf now supports %z
* Don't use -fno-tree-loop-distribute-patterns if the compiler doesn't
support it (@hannesm)
* Remove "Cannot handle page request order %d!" warning - just return
NULL on OOM
* Add opam file for easier installation

On the normal Trusty cubieboard2 image I can install minios-xen fine, but on Vivid I get an error:

$ opam install minios-xen

[ERROR] The compilation of minios-xen failed at "make debug=n".

mirage-xen-minios.0.7.0 was OK because of:

https://github.com/talex5/xen/commit/804d40b4fe00d68e1be3160f8bcc0d94f3d4edf0

I'm guessing that the difference in this image is that it has GCC-4.9.2 instead of 4.8.x, but I'm not certain.
