Subject: [PATCH] haskell: disable library profiling for static executables

Haskell packages overridden with justStaticExecutables
(like cabal-install, stack, pandoc, darcs, etc.) don't provide
libraries in the end result so it's futile to build them with library
profiling enabled because it will just take extra time.
