Ah yes, looks like it's "xen-gnt.unix" I need.

Without that, I get lots of link errors, e.g.

/home/tal/.opam/4.01.0/build/xen-gnt.2.0.0/_build/lib/gnt.ml:105:
undefined reference to `stub_gnttab_map_onto'

I can't see a direct way to control whether xen-gnt.unix gets built.
It seems it only gets built if the Xen headers are present.
