Need an option to enable/disable testing in the build process.

It's great that there are tons of tests, but it would be much better if that were an
option (or even an option to disable), but if it is, it's not clear.  With the fink
package, we have the option to run tests, but without support from the go build system,
I can't split off the tests.  Since every user installs from source, this is a serious
pain point, especially on wimpier devices like the macbook airs.  Like less than a
minute to build go and > 5 minutes of running tests.
