 If there is {{{-hide-package}}} with {{{--make}}} all packages are hidden
 (as if no {{{--make}}} mode was enabled).

 It causes problems especially given the current migration from mtl to
 transformers + monads-fd/monads-tf. Pragma {{{ {-# OPTIONS_GHC -package
 xyz #-} }}} does not work as well.

 Currently workarounds:

  - Hide package manually. As mtl is still used it might or might not be an
 option. Also it requires user intervention for configuration.
  - Specify the all packages. Not an option as configurated program does
 not know all packages configuration file is using in advance.
  - Do not hide packages. Requires extentions like PackageImports which
 makes the configuration harder for newcommers which tries to configure
 program.
