Maybe you'd better read the FHS again to double check that you're adhering.

http://www.pathname.com/fhs/pub/fhs-2.3.html#VARCACHEAPPLICATIONCACHEDATA

Purpose:

  /var/cache is intended for cached data from applications. 
  Such data is locally generated as a result of time-consuming 
  I/O or calculation. The application must be able to regenerate 
  or restore the data.

I fail to see how git can regenerate the symlinks...
