It's actually used unset a couple of lines after this patch, but this
just resolves it in one place instead of calling
$(kube::golang::host_platform) twice.
Because of Fedora's crazy packaging guidelines, go install basically
isn't allowed. So allow us to use go build instead of go install.
test-integration also needs to accept the flag to be able to pass it
along to the build function.
* Rewrite a bunch of the hack/ directory with modular reusable bash libraries.
* Have 'build/*' build on 'hack/*'. The stuff in build now just runs hack/* in a docker container.
* Use a docker data container to enable faster incremental builds.
* Standardize output to _output/{local,dockerized}/bin/OS/ARCH/*. This regularized placement makes cross compilation work.
* Move travis specific scripts under hack/travis
With new dockerized incremental builds, I can do a no-op `make quick-release` in ~30s. This is a significant improvement.
