ghc module and Haskell static linked executables


A heads-up that I am planning to move Haskell executables to static linking
in F30.
This to improve the experience with the new ghc module: currently most of
the Haskell executables (except hscolour and hedgewars I believe) are
dynamically linked which conflicts
with modular ghc, making it painful to use.

Switching to Haskell static linking means that cabal-install, pandoc,
ShellCheck, git-annex, etc will continue to work even if one installs a ghc

reflect this.
