As the title says, I get a strange error building crosstool-ng for mipsel architecture under Alpine in Docker. Any ideas? To me it looks like some kind of incompatibility between the host toolchain and the target toolchain but I'm no expert in this sort of thing.
Here is my Dockerfile:
FROM alpine:3.10.2
RUN apk add bash
SHELL ["/bin/bash", "-c"]
RUN apk add build-base
RUN set -o xtrace ; set -o errexit ; set -o nounset ; set -o pipefail ; mkdir -p /opt/ctng ; cd /opt/ctng ; wget http://crosstool-ng.org/download/crosstool-ng/crosstool-ng-1.24.0.tar.bz2 ; [ "$(sha256sum ./crosstool-ng-1.24.0.tar.bz2 | cut -d " " -f 1)" == "d200d1ea5e2056c60d2b11b3f2721d30e53e817e1e0050fffaca074864e2f523" ] ; tar -xf ./crosstool-ng-1.24.0.tar.bz2 ; mv ./crosstool-ng-1.24.0 ./ctng
