How to share files/folders across git repo?

Question

I have a git repository, inside there are files/folders, that I want to share across repo.

repo/
     .git/
     html-coding
          css-shared
     js-app
          css-shared
          ttf-shared
     font-files
          ttf-shared

Using Submodules for this task looks like overkill. At times of SVN I've used snv:externals flag, which worked just fine for my purposes.

Subtree is again referencing to external repos, which I don't need at all. Something simple like symbolic links would be acceptable. But I need it cross-platform, since my devs are on Mac, Win and Linux.

Using Submodules for this task looks like overkill

Using submodules is the right solution, especially since they now can follow the latest commit of a branch (since git1.8.2, March 2013).
In that aspect, they act as svn:external.
