docker build with FROM argument from build argument fails

[rn]

With a Dockerfile like this:

ARG IMAGE
FROM ${IMAGE}
RUN touch /${IMAGE}

and a docker invocation like this:

docker build -t foo --build-arg IMAGE=alpine:3.6 .

I get an error like this:

Sending build context to Docker daemon

error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.35/build?buildargs=%7B%22IMAGE%22%3A%22alpine%3A3.6%22%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&session=69f2bc8de54890341a74adacb2879d17d2248d4ea5261f38a111839f2efdb740&shmsize=0&t=foo&target=&ulimits=null: invalid reference format: repository name must be lowercase

This works fine on Linux and Docker for Mac.

The daemon log only contains:

DEBU[2017-11-29T15:48:51.141496100Z] Calling GET /_ping
DEBU[2017-11-29T15:48:51.144511500Z] Calling POST /session
