What version of Go are you using (go version)?
$ go version
go version go1.14rc1 linux/amd64
Does this issue reproduce with the latest release?
I hit this with golang:1.14-rc-alpine docker image, the error does not happen in 1.13.
What operating system and processor architecture are you using (go env)?

What did you do?
Clone https://github.com/ethereum/go-ethereum, replace the builder version in Dockerfile to golang:1.14-rc-alpine (or use the Dockerfile from below), then from the root build the docker image:
$ docker build .
FROM golang:1.14-rc-alpine
RUN apk add --no-cache make gcc musl-dev linux-headers git
ADD . /go-ethereum
RUN cd /go-ethereum && make geth
What did you expect to see?
Go should run our build scripts successfully.
