    platform: Remove .ldata/.lrodata/.lbss sections from ldscript
    
    The kernel is compiled with '-mcmodel=kernel', so the compiler never
    emits the large model sections (e.g., .ldata/.lrodata/.lbss).  Therefore,
    remove such sections from the kernel linker scripts.
    
    This change has another major benefit: the '.bss' section now correctly
    lies at the end, so the linker does not need to allocate real file space
    to store the BSS section.  As a result, the kernel file size is reduced
    by 14MB (e.g., stripped kernel reduces from 29MB to 15MB)!  Meanwhile,
    the following gold linker warning is also fixed:
    ```
    /usr/libexec/binutils234/elf/ld.gold: warning: script places BSS section in the middle of a LOAD segment; space will be allocated in the file
    ```
