    [linker] fix armv7 & add aarch64
    
    This adds Global Offset Table logic, as well as PLT like logic for armv7
    and aarch64; which replaces the preexisting symbolExtras logic, by
    placing the PLT tables next to the separtely loaded sections. This is
    needed to ensure that the symbol stubs are in range.
