[PATCH] get rid of "Just" string in __GLASGOW_HASKELL_LLVM__ define for invoked GCC The patch fixes invoked GCC command line -D parameter from -D__GLASGOW_HASKELL_LLVM__=Just <LLVM version number> to correct -D__GLASGOW_HASKELL_LLVM__=<LLVM version number>, e.g. -D__GLASGOW_HASKELL_LLVM__=Just 32 fixed to -D__GLASGOW_HASKELL_LLVM__=32 for LLVM 3.2
