Wrong error message for TH when GHCi is not enabled

A user reported this confusing error message:

Data/FileEmbed.hs:69:15:
    Template Haskell bracket illegal in a stage-1 compiler
      [| stringToBs |]

The compiler was not stage-1, but:

ghc --info
 [("Project name","The Glorious Glasgow Haskell Compilation System")
 ,("Project version","7.0.4")
 ,("Booter version","7.0.4")
 ,("Stage","2")
 ,("Build platform","powerpc-unknown-linux")
 ,("Host platform","powerpc-unknown-linux")
 ,("Target platform","powerpc-unknown-linux")
 ,("Have interpreter","NO")
 ,("Object splitting","YES")
 ,("Have native code generator","YES")
 ,("Have llvm code generator","YES")
 ,("Support SMP","YES")
 ,("Unregisterised","NO")
...
 ]

So it looks like the problem is not stage-1, but the fact that ("Have interpreter","NO").

So the error message should report that the Template Haskell extension requires that ghc is built with ghci/interpreter support.
