I have no idea where the problem might be here. As far as I know Go itself doesn't do anything with manifest files at all.

Can you add the output of GOARCH=386 go build -x with both Go 1.6 and 1.7beta? Thanks.

The difference is that go-1.6 makes a step in between "compile" and "link", which is "pack". This is not done in go-1.7beta1

go-1.6:
GOARCH=386 go build -x

Thanks. I think this is an unexpected consequence of the fix for issue #14123. For you, CGO_ENABLED=1 for amd64 but CGO_ENABLED=0 for 386. You could probably make your case work by writing

CGO_ENABLED=1 GOARCH=386 go build

I will see if I can fix this for 1.7.
