[Xen-devel] [PATCH v4 3/3] enable QEMU for ARM builds

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Build qemu-xen on ARM and ARM64: it is used to provide the PV backends,
disk and framebuffer in particular.

Ideally we would also modify the configure options to only build what is
necessary: a machine just for PV backends. However that is a work in
progress and not yet available in QEMU (see
http://marc.info/?l=qemu-devel&m=139082425718379&w=2). So we just build
the usual i386 target, even though no i386 emulation is going to be done
by qemu-xen on ARM.
