      Do not #include external header files when compiling via C · c245355e
      Simon Marlow authored
      This has several advantages:
      
       - -fvia-C is consistent with -fasm with respect to FFI declarations:
         both bind to the ABI, not the API.
      
       - foreign calls can now be inlined freely across module boundaries, since
         a header file is not required when compiling the call.
      
       - bootstrapping via C will be more reliable, because this difference
         in behavour between the two backends has been removed.
      
      There is one disadvantage:
      
       - we get no checking by the C compiler that the FFI declaration
         is correct.
      
      So now, the c-includes field in a .cabal file is always ignored by
      GHC, as are header files specified in an FFI declaration.  This was
      previously the case only for -fasm compilations, now it is also the
      case for -fvia-C too.
