Don't error out if ${go_pkg_dir} already exists
I have 'make' aliased to 'make -j4' for various reasons, and that's always worked fine for Kubernetes in the past. But it recently broke because EEXIST errors from this symlink creation are fatal. So make them not fatal, because if the path already exists, why try to create it again? It exists because two invocations of setup_env() are run in parallel due to the -j4, and they race to create the symlink and one obviously fails.

Also build the hyperkube docker image on-the-fly.
This is only a temporary fix until the proposal in issue
https://github.com/kubernetes/kubernetes/issues/28630 is implemented.
Also, the new build/deployment method completely obviates this step.
We use debian image instead of busybox and do not build hyperkube as a
static binary yet. Wait until PR
https://github.com/kubernetes/kubernetes/pull/26028 is merged to build
static hyperkube binaries.
Repro case:
$ make clean generated_files
$ hack/update-generated-protobuf.sh
This would complain about not finding `fmt`, and it was indicating the wrong
GOROOT. The problem was that the first step built binaries for generating
code, which *embeds* the value of GOROOT into the binary. The whole tree was
bind-mounted into the build container and then JUST the dockerized dir was
mounted over it. The in-container build tried to use the existing binaries,
but GOROOT is wrong.
This change whites-out the whole _output dir.
I first made just an anonymous volume for _output, but docker makes that as
root, which means I can't write to it from our non-root build. So I just put
it in the data container. This seems to work. The biggest change this makes
is that the $GOPATH/bin/ and $GOPATH/pkg/ dirs will persist across dockerized
builds.
The KUBE_VERBOSE environment variable sets the verbosity level to
use. Log messages can specify a verbosity by setting the V
variable. e.g.
V=2 kube::log::info foo bar
Would only print "foo bar" if $KUBE_VERBOSE >= 2.

Build Darwin test binaries on OS X when KUBE_FASTBUILD is set
Without this, on OS X, test binaries would not be built for the local ARCH, and test scripts fail with an obscure error due to not being able to find the correct binary to run.
This makes the behavior on OS X more consistent with Linux.
Tested on OS X and Linux.

Improve the speed of do-nothing build.
As @thockin found out here https://github.com/kubernetes/kubernetes/issues/24518, vast majority of the do-nothing build time is spent in rebuilding the test binaries. There is no staleness check support for test binaries.
This commit implements the staleness checks for test binaries and uses them while building packages.
On my workstation, do-nothing hack/build-go.sh time goes from ~20 secs to ~4 secs, of which only ~1 sec is from doing test binary staleness check now (as opposed to ~17 secs it took to build the test binaries before). I did some experiments to bring this time down to <1 sec. I measured using go test -bench, but it was not very useful in this case. I believe, a vast majority of that ~1 second is being spent in fork/exec and piping the results back to the staleness check program along with the ser-deser involved, but it needs to be validated. Not a proof, but to provide some supporting evidence to this claim, running `go list -f format packages` in the shell takes about 600ms irrespective of what's in the format.
Tests are TBD. I am still trying to figure out how to test this, but I would like to get early feedback

Our `realpath` and `readlink -f` functions (required only because of MacOS,
thanks Steve) were poor substitutes at best. Mostly they were downright
broken. This thoroughly overhauls them and adds a test (in comments, since we
don't seem to have shell tests). For all the interesting cases I could think
of, the fakes act just like the real thing.
Then use those and canonicalize KUBE_ROOT. In order to make recursive calls of
our shell tool not additively grow `pwd` we have to essentially make the
sourcing of init.sh idempotent.

Fix spacing in usage_from_stdin and info_from_stdin (issue #24186).
If "a" is a bash array, then the syntax to append the contents of $line as a
new element to the array is a+=("$line"), not messages+=$line
Using the former syntax just seems to append to the first element, creating a
long string and thus losing newline information.
Fixing this allows us to drop some empty lines from invocations of
usage_from_stdin.
