goreleaser: Invalid binary for alpine amd64 (x86_64)

Host machine:

$ uname -a

$ docker run --rm golang:latest go version
go version go1.8.1 linux/amd64

The problem:

$ docker run --rm golang:alpine \
  /bin/sh -c 'apk update --no-cache \
           && apk add --no-cache ca-certificates git wget \
           && update-ca-certificates &>/dev/null \

$ docker run --rm golang:latest \

           && readelf -l /tmp/goreleaser/goreleaser | grep "program interpreter"'
...
[Requesting program interpreter: /lib64/ld-linux-x86-64.so.2]

The reason is that /lib64/ld-linux-x86-64.so.2 doesn’t exist at alpine linux.

So, if I get 32bit app for alpine, then it is ok

$ docker run --rm golang:alpine \
  /bin/sh -c 'apk update --no-cache \
           && apk add --no-cache ca-certificates git wget \
           && update-ca-certificates &>/dev/null \

goreleaser version dev, commit none, built at unknown

So, could you also build binary for alpine ?
