    bsp/native: Fix linker script for native build
    
    Previously linker script was generated by gcc on Ubuntu.
    It turned out that it will not work on Fedora builds.
    
    Now link time tables are ADDED to default linker script
    and default linker script is not replaced by arbitrary
    version that works only with some toolchains.
    
    Key factor is that .rodata section is an anchor point
    to put link time tables entries.
