Revert previous, not all platform defines seg_reset_stack_size.
Remove all references to seg_reset_stack_size to avoid confusion

    1111 * This preloader uses a stack segment allocated in cluster 0, defined
    12  * by the seg_reset_stack_base and seg_reset_stack_size parameters in ldscript.
     12 * by the seg_reset_stack_base parameters in ldscript, of size 0x10000 (64k)
    1313 * - Processor 0 uses a larger stack:         64 Kbytes.
    1414 * - Other processors use a smaller stack:    512 bytes.
    15  *     => the seg_stack_size cannot be smaller than 0x90000 bytes (576 K).
     15 *     => the stack size cannot be smaller than 0x90000 bytes (576 K).
    1616 * Those stacks can be used by both the preloader and the boot-loader code.
