For sure, that's not on-purpose.

Now, I fail to see how the remporary repository would linger after a
successfull download. Here's what the script does:

    repodir="${BR2_DL_DIR}/${basename}"

    if [ -n "$(${GIT} ls-remote "${repo}" "${cset}" 2>&1)" ]; then
        printf "Doing shallow clone\n"
        ${GIT} clone --depth 1 -b "${cset}" --bare "${repo}" "${repodir}"
    else
        printf "Doing full clone\n"
        ${GIT} clone --bare "${repo}" "${repodir}"
    fi

    pushd "${repodir}"
    ${GIT} archive --prefix="${basename}/" -o "${output}.tmp" --format=tar
    "${cset}"
    gzip -c "${output}.tmp" >"${output}"
    rm -f "${output}.tmp"
    popd

    rm -rf "${repodir}"

So, unless there is something I'm missing, the last statement should get
rid of the temp repo...

Lemme try...

Nope, the repository is properly removed here:

    $ make libllcp-source
    [--SNIP--]
    >>> libllcp cf0c4b3c9df98851c6092c130192130c3f5a46bd Downloading
    Doing full clone

So, no lingering clone...
