Thanks.

Can userspace require the build system to keep using some Kconfig symbol
by doing tests like these? Anyhow, if that's the only tool then
XEN_PRIVILEGED_GUEST can be dropped. XEN_PRIVILIGED_GUEST should always
be equal to XEN_DOM0 so this if () test will evaluate identically with
the sub-test for CONFIG_XEN_PRIVILIGED_GUEST removed.
