cmd/gomobile: pass -a build flag to go build command

The gomobile build command wraps "go build" and parses many build
flags including "-a", but it was not actually passing the "-a" flag
through to the underlying go build command.

The "-a" flag forces a rebuild of packages and dependencies, which
is useful for ensuring clean builds when needed.

Add the missing code to pass the "-a" flag through to the go build
command when buildA is true, matching the pattern used for other
build flags like "-x" and "-gcflags".

Fixes golang/go#76466.

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 golang.org/wiki/Mobile to install the gomobile command, build the basic and the bind example apps.


Contributions to Go are appreciated. See https://go.dev/doc/contribute.
