 `cabal configure` currently includes the test suite dependencies even
 without `--enable-tests`. This means that `cabal install <some lib>` will
 pull in e.g. test-framework, even though that isn't necessary to install
 the library.

 For example, given this configuration:

 {{{
 library
   ...
   build-depends:
     base >= 3 && < 4.4,
     bytestring < 1.0,
     parsec >= 2.0 && < 3.1.1

   if !os(windows)
     build-depends:
       unix >= 2 && < 3

 test-suite simple
   ...
   build-depends:
     base < 4.4,
     bytestring < 0.10,
     HUnit < 1.3,
     network,
     test-framework < 0.4,
     test-framework-hunit < 0.3

 test-suite uri
   ...
   build-depends:
     base < 4.4,
     HUnit < 1.3,
     network,
     test-framework < 0.4,
     test-framework-hunit < 0.3
 }}}

 we get this:

 {{{
 $ cabal configure -v
 ...
