 As of now, ghc creates and uses a "$HOME/.ghc" directory. This is annoying
 to those who like to keep their $HOME directory clean through use of the
 XDG_CONFIG_HOME variable. Specifically, it's nice to have all
 configuration files in "$HOME/.config" instead of polluting "$HOME".

 It would be great if ghc could create and use its configuration directory
 in the configuration directory specified by the user.
