The new git-submodule.sh script writes .git-submodule-status to
the source directory every time no matter what. This makes it conditional.

I compile out of tree on a remote guest system where I mount the
source directory as "readonly" and build directory as "rw" and
scripts/git-submodule.sh tries writing to the source directory even when
I manually update modules on a host machine which is quite annoying.
Is this something acceptable? Or I am missing something here?
