    compiler, libgo: don't pad sparc64-linux epollevent

    Change the compiler to not add zero padding because of zero-sized
    fields named "_", since those can't be referenced anyhow.

    Change the sparc-linux64 epollevent struct to name the alignment
    field "_", to avoid zero padding.

    Fixes PR go/103847

            field "_".
