The `RUN make build` step fails in docker

[AbdulrhmnGhanem]

After pulling the latest updates in https://github.com/kitspace/gitea/tree/rebase-4, the RUN make build step fails with the error

no rule to make target 'modules/public/bindata.go', needed by 'gitea'. stop.

This isn't the case if I run make TAGS="bindata sqlite sqlite_unlock_notify" make build locally.
It also fails when builidng with the original docker file Dockerfile. Though cloning go-gitea/gitea and running docker build doesn't cause this error.

The output of git diff --name-only HEAD upstream/main is shown below, I am not sure what changes can cause this error.

git clone https://github.com/go-gitea/gitea && cd gitea && docker build . -t tag builds the image successfully!
Even git clone https://github.com/kitspace/gitea && cd gitea && docker build . -t tag builds it!

@kasbah, could you reproduce the error in the first command?

[kasbah]

git fetch upstream && git checkout upstream/main && docker build . -t my_tag 

fails with the same error for me. i didn't checkout the rebase-4 branch before.

I managed to reproduce the error apart from our changes

mkdir test
cd test
git init .
git submodule add https://github.com/go-gitea/gitea
cd gitea
docker build . -t tag

The command '/bin/sh -c if [ -n "${GITEA_VERSION}" ]; then git checkout "${GITEA_VERSION}"; fi  && make clean-all build' returned a non-zero code: 2

A wild guess is that this is a bug in Golang itself; it doesn't handle submodules properly.
