LOCALVERSION in setlocalversion

[Haojian Zhuang]

Hi,

In scripts/setlocalversion under linux kernel tree, the scripts seems
a little strange.

# scm version string if not at a tagged commit
if test "$CONFIG_LOCALVERSION_AUTO" = "y"; then
        # full scm version string
        res="$res$(scm_version)"
else
        # append a plus sign if the repository is not in a clean
        # annotated or signed tagged state (as git describe only
        # looks at signed or annotated tags - git tag -a/-s) and
        # LOCALVERSION= is not specified
        if test "${LOCALVERSION+set}" != "set"; then
                scm=$(scm_version --short)
                res="$res${scm:++}"
        fi
fi

LOCALVERSION isn't assigned in any place. Only CONFIG_LOCALVERSION
can be assigned in .config file.
Why do we need to check LOCALVERSION at here?

Thanks
Haojian
