Gitaly install puts go files into home directory

I noticed an extra directory appear on by built from source Gitlab installation

${HOME}/go

It seems to be created by Gitaly but I'm not sure how to get it to install those files in the ${HOME}/gitlab/gitaly directory or at least somewhere under ${HOME}/gitlab

This is the code that generates it:

# Update gitaly
cd ${GITLAB_HOME}/gitaly
git fetch --all --tags --prune
git stash
git checkout v$(<${GITLAB_INSTANCE}/GITALY_SERVER_VERSION)
make

What's worse is the files under ${HOME}/go are read only making it more of a pain to rm -rf them
