golang-go-linux-amd64 2:1.1.2-2ubuntu1 (amd64 binary) in ubuntu trusty

 This package contains the Go standard library,
 compiled for linux_amd64.
 .
 This package is just one of a number of packages, each providing the Go
 standard library for a specific operating system/architecture combination.
 Go supports cross-compilation, so each of these packages is useful on any
 architecture.
 .
 The files contained in this package are independent of the host architecture,
 that is, you can use golang-go-linux-amd64 to generate a binary for
 linux_amd64, even though you are executing the Go compiler on linux_386.
