 It would be really, really handy for us to be able to use top-level if
 constructs, such as:

 if os(linux)
   executable run-tests
   main-is: ...
   ghc-options: ...

 if os(foo)
   executable program
   main-is: ...
   ghc-options: ...

 (Specifically, we need it in cases like this, where tests run on a
 different OS than the code will be run on.)
