The Go toolchain used to require that we rebuild the compiler and
friends (the cgo command) when building a cgo-enabled cross compiler.
This meant that gomobile init used to invoke make.bash in a temporary
copy of the GOROOT. This works, but brings with it several
complications, including needing to use -toolexec when invoking the
go tool, finding a boostrap copy of Go 1.4, long initialization
times, and a variety of unusual failure modes.
Fortunately we don't need our own compiler any more. All that's
necessary is building the standard library for the cross-compilation
targets and making sure the right C compiler is used when calling
go build (as it always was). This means most of the initialization
process can be replaced with a carefully invoked 'go install std'.
While here, remove the source install instructions (most of it is
documented already, and the final step, choosing the right git
revision should be within the skills of anyone using pre-release
software.) Some other documentation is changing because it's been a
while since go generate was run.

Also add a very simple test for gomobile build, some
documentation cleanup, and the -o flag for bind.

The user may have set GOBIN, in which case the existing go command is
overwritten. I cannot think of any relevant environment variables the
user would set, so the easiest thing is not to use them at all.
While here, fix the unit test I broke in cl/10319.

Instead of trying to preserve the unpacked NDK, this stores the
downloaded archives in GOPATH/pkg/gomobile/dl and completely
rebuilds on reinitialization.
Also introduce checking that the version of Go we are using to do
the build matches the GOROOT we are building from.
