[Qemu-devel] [PATCH v2 1/9] configure: change CONFIG_XEN_BACKEND to be a target property

[Stefano Stabellini <sstabellini@kernel.org>]

CONFIG_XEN_BACKEND is currently set when the host supports Xen,
regardless of the chosen targets. As a consequence, Xen backends can be
enabled even on targets that don't support Xen.

Fix the issue by setting CONFIG_XEN_BACKEND only for targets that
support Xen.
