[PATCH v2 06/10] arm: compile libxenguest

[Stefano Stabellini <stefano.stabellini@eu.citrix.com>]

Introduce an empty implementation of the arch specific ARM functions in
xc_dom_arm.c.
Also provide empty implementations of xc_domain_save, xc_domain_restore
and xc_hvm_build_target_mem when CONFIG_HVM or CONFIG_MIGRATE are not
set.
