Comment:

 Now all builds fine and does not crash ghc!
 Thanks!

 Some stats (both runs are '''-O2 -j4 --make'''):

 highlighting-kate alone now takes about
     ~3.7GBs RAM

 'selfcontained-eater-ghc-7.8-rc2.tar.gz' now takes
     ~7.1GBs RAM
 and contains 452 modules

 Which is very sane for amd64.
