    binutils: Bail out if gold is used on 32/64 bit RISC-V
    
    gold is not supporting risc-v yet and, this will cause subltle errors
    during build e.g. autoconf not finding certain features like visibility
    and it could take a while to unwind the problem. Its better to error out
    early
    
    Remove dwp and ld.gold for rv32 as well
