    kernel linker: do not read debug symbol tables for non-debug symbols

    In particular, this prevents resolving locals from other files.
    To access debug symbol tables, add LINKER_LOOKUP_DEBUG_SYMBOL and
    LINKER_DEBUG_SYMBOL_VALUES kobj methods, which are allowed to use
    any types of present symbols in all tables.
