Passing -optP-traditional to the preprocessor breaks the build.
The build of 7.0.1 breaks when the preprocessor is explicitly specified by the -pgmP option and the -traditional flag is passed using -optP-traditional. The trouble is that most of ghc requires -traditional flag, but .cmm files don't. The -optP-traditional option needs to be filtered out from the options passed when compiling .cmm files.
