cmd/gomobile: run go install in c-shared mode only if NDK is set

A check for the NDK was missing from the pre-install of the standard
library for each Android GOARCH. If the NDK wasn't set, the go install
invocation would silently use the host GOARCH and GOOS and only fail if
no host gcc was found for runtime/cgo.

Discovered while setting up gomobile on a clean Windows machine.

With the go 1.10 cache go installing the standard library might be
pointless, but let's wait a little before removing it.

Go support for Mobile devices

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
