    x86: remove stack definition in linker script
    
    In order to prepare the ramstage to be linked by the rmodule linker the
    stack needs to be self-contained within the ramstage objects. The
    reasoning is that the rmodule linker provides a way to define a heap,
    but it doesn't currently have a region for the stack.
    
    The downside to this is that memory footprint of the ramstage can change
    when compared before this change. The size difference stems from the
    link ordering of the objects as the stack is now defined within
    c_start.S. The size fluctuation ranges from 0 to CONFIG_STACK_SIZE - 1
    because of the previous behavior or aligning to CONFIG_STACK_SIZE. It
    should be noted that such an alignment is unnecessary for 32-bit x86 as
    the alignment requirement for the stacks are 4 byte alignment. Also the
    memory footprint is still dominated by CONFIG_RAMTOP and CONFIG_RAMBASE.
