The documentation needs to explain that CGO must be disabled for cross compilation.

For instance, with correct (and documented) environment variables set to:

export GOROOT=<whatever your goroot>
export GOARCH=arm
export GOOS=linux

but building on an OS X platform (amd64, darwin), the build fails with:

...
runtime/cgo
go build runtime/cgo: cannot use cgo when compiling for a different operating system
...

Document that CGO must be disabled via:

export CGO_ENABLED=0

Comment 2:

see also issue #4714.
as issue #4714 is not labeled Go 1.1, we need to fix this before Go 1.1
(i suggest we treat cgo as disabled by default when doing cross OS
cross-compilation, then we don't need to document; that is, cmd/go
should do the right thing by default).

Comment 3:

Deferring the doc topic. It's a big topic and we have nothing on it now. When we have a
cross-compilation doc, we'll make the topic clear.
Opening a new bug to address minux's point.
