The skylake-based Chromebooks use a separate verstage which runs just after bootblock and prior to romstage. However, that config is not enabled for coreboot.org so when C_ENVIRONMENT_BOOTBLOCK changes were done it wasn't observed that the Chromebook config failed because 2 _start symbols were present. Remedy this failure by using the common car_stage_entry symbol for taking over control flow.
