    compiler/riscv: Add alternative toolchain
    
    riscv64 toolchain currently associated with hifive1 board
    is the original toolchain from Sifive1.
    For some time now there is alternative that has some very minor
    differences.
    This adds this alternative toolchain in case someone wants to used it.
