Suggestion we add this little detect and switch. One issue i see with
attempting to detect GOBIN is that it doesn't HAVE to be set (ie: there
can be a default). This i would think is a good quick compromise to
un-confuse @rootulp and (potentially) other devs and make this behavior
more delightful most of the time. IF not, we should close this and the
other issue.
