I see, you just do the git-new-workdir for every submodule before "git
submodule update" is run, and "git submodule update" respects the
setup. That should work, yes, but it abandons the idea of putting the
.git directory of the submodule in .git/modules/foo..

I've managed to fork git-new-workdir into git-new-module-workdir and
using it I've reenabled the --with-linked-git ./configure option. But
I've changed the semantics a bit.

You have a unique special "master" branch that serves as
reference, and you link everything to there. I work slightly
differently:

1) I have bare git repos for core and the submodules

2) My master checkout is in directory "libreoffice-4.2" and when the
   branch "libreoffice-4-2" is created, I switch to it and create a
   new "libreoffice-4-3" checkout.

So, to cater for my needs, "--with-linked-git" now does not point to a
full checkout, but to the parent directory of all submodule git
repositories, where each has to be named after their submodule
name. In your scenario, pointing it to ~/libo/master/ or
~/libo/master/.git/modules should both work. Let me know if it does.

Not really, the "submodule update" checkouts a specific SHA1-ID,
without reference to any branch anyway.
