ARM memory layout fixes: the abort-stack is now set up in the correct RAM area, and the BSS is zeroed out as it should be. Furthermore, the magic variables 'armboot_end' and 'armboot_end_data' of the linker scripts are replaced by '__bss_start' and '_end', resp., which is a further step to eliminate unnecessary differences between the implementation of the CPU architectures.
