hallgren 836b5f6afa gf.cabal: removing -O2 ...

Removing "ghc-options: -O2" from gf.cabal has the following advantages:

+ Compiling GF is faster (time drops from 182s to 142s on my laptop)
+ Compiling the RGL is faster (time drops from 159s to 155s on my laptop)
+ Without the hardwired optimization level, the 'cabal configure' options
  --enable-optimization=<n> and --disable-optimization work as expected
  (so if you still want -O2, use --enable-optimization=2)
+ GF can be compiled with ghc-7.2.2 and ghc-7.4.1 (-O2 triggers a bug in
  these versions of ghc, it seems. Another workaround, discovered by
  Sergei Trofimovich, is to use -O0 in Data.Binary.)
