Your version test for gold isn't robust: if the major version >= 3,
then presumably split stack is supported.  And since you have numbers,
I suggest not trying to use switch, but instead writing something like
    if expr "$gold_minor" == 25; then
        ...
    elif expr "$gold_minor" > 25; then
        ...
    fi

If that is fixed, I'm fine with the libgo part of this patch.
