  * Lift the restriction that libraries must have exposed-modules
  This allows libs that have only private modules or C code. This
  might be used to make libs that have non-exposed modules and only
  export C APIs. It could also be used to make packages that consist
  only of C code. That might be useful for bindings where it may
  make sense to split the C and Haskell code into separate packages.
