Mc: No se puede leer la configuración del host del entorno [ARM]

Mi Dockerfile

FROM alpine:3.9

RUN \
    apk add --no-cache ca-certificates && \
    apk add --no-cache --virtual .build-deps curl && \
    ARCH=$(uname -m) && if [ "$ARCH" = "x86_64" ] ; then ARCH="amd64" ; else ARCH="arm" ; fi && \
    curl https://dl.min.io/client/mc/release/linux-$ARCH/mc > /usr/bin/mc && \
    chmod +x /usr/bin/mc && apk del .build-deps
ENV MC_HOST_mcplay ${MC_HOST_mcplay}

ENTRYPOINT ["mc"]

Comportamiento esperado

docker run --rm -e "MC_HOST_mcplay=https://Q3AM3UQ867SPQQA43P2F:[email protected]:9000" ramosisw/mc:arm -- ls mcplay

Comportamiento real

docker run --rm -e "MC_HOST_mcplay=https://Q3AM3UQ867SPQQA43P2F:[email protected]:9000" ramosisw/mc:arm -- ls mcplay
mc: <ERROR> Unable to stat `mcplay`. Requested file `mcplay` not found

Pasos para reproducir el comportamiento

En AMD64 funciona pero no en ARM

Para reproducir, solo se ejecuta el siguiente comando en el arco del brazo (como Raspberry Pi con Docker)

docker run --rm -e "MC_HOST_mcplay=https://Q3AM3UQ867SPQQA43P2F:[email protected]:9000" ramosisw/mc:arm -- ls mcplay
