cmd/gobind: exec the test binary as gobind and log only stderr by default

Using the test binary as the "gobind" command not only avoids the
overhead of recompiling the command, but also allows commands like "go
test -race" to actually test the requested configuration of the

Logging stderr and stdout separately — and logging only stderr by
default — makes the failure messages much easier to spot. (Logging the
combined output as before produced a massive wall of text that tends
to bury the actual errors.)

For golang/go#56292.

Go support for Mobile devices

Go Reference

The Go mobile repository holds packages and build tools for using Go on mobile platforms.

Package documentation as a starting point:

Caution image

The Go Mobile project is experimental. Use this at your own risk. While we are working hard to improve it, neither Google nor the Go team can provide end-user support.

This is early work and installing the build system requires Go 1.5. Follow the instructions on to install the gomobile command, build the basic and the bind example apps.

Contributions to Go are appreciated. See
