    builtools: Make abi_gen.sh less prone to errors
    
    The mold linker has more hidden symbols and we would need to filter them out
    with nm, where objdump tells us which symbols are actually hidden. So we just
    need to filter out whatever is hidden.
    
    The use of awk makes it also easier to get what we want.
