    symbols: centralize and re-arrange $(all_symbols) calculation
    
    For one there's no need for each architecture to have the same logic.
    Move to the root Makefile, also to calculate just once.
    
    And then re-arrange to permit FAST_SYMBOL_LOOKUP to be independent of
    LIVEPATCH, which may be useful in (at least) debugging.
