Do not #include external header files when compiling via C
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.
