I remember the relative paths for submodules were added to make working 
with several clones of the GHC repo (to lower rebuild cost for 
simultaneous branches or similar) easier.

With relative paths, one can make a second local clone from the first 
one and all references to all submodules will share local data.

That said, this does get in the way sometimes. I changed back to 
absolute paths in my GHC fork quite a while back.
