Running full make.bash for bootstrapping platforms

For some reason, using go tool dist didn't work for me on an OS X host and Go 1.3.3.  When cross-compiling using gox, it complained that the target platforms still needed to be bootstrapped.

So, I changed the code to instead run ./make.bash --no-clean as described in [your blog](https://inconshreveable.com/04-30-2014/cross-compiling-golang-programs-with-native-libraries/) and that took care of the problem.
