In some cases, when we don't use CONFIG_SPL_FRAMEWORK nor are we on PowerPC using their specific SPL/TPL framework, we need to specify the start.S file to use for these typically very constrained systems. Do this within the Makefile logic, rather than introducing a string-based CONFIG option, as this would get slightly complex to do in Kconfig for a very limited number of users.
