In order to do that, virNodeSuspendSupportsTargetPMUtils() and virSystemdPMSupportTarget() are created even when pm-utils and dbus are compiled out, respectively, but in that case returning -2 meaning "unavailable" (this return code was already used for unavailability before). Error is reported in virNodeSuspendSupportsTarget() only if both functions returned -2, otherwise the error (or success) is properly propagated up the stack.
