 If I compile with `-dynamic-too`, ghci still re-interprets the source code
 instead of finding the `Test.dyn_o` file.

 {{{
 $ inplace/bin/ghc-stage2 -O1 -dynamic-too -c Test.hs
 $ inplace/bin/ghc-stage2 --interactive Test
 GHCi, version 7.7.20130710: http://www.haskell.org/ghc/  :? for help

 [1 of 1] Compiling Test             ( Test.hs, interpreted )
 Ok, modules loaded: Test.
 *Test>
 }}}

 I'm guessing that ghci sees the `.o` file isn't suitable for dynamic
 loading and then falls-back to the interpreter without first checking for
 the `.dyn_o` file.

 ghci loads `Test.o` as expected if I instead compile with `-dynamic`.

 I'm on OS X 64-bit, if that might matter.
