 Validate produces the following error message:
 {{{
 In file included from rts/dist/build/ffi.h:58:0: error:
     0,
                      from rts/Adjustor.c:46:

 rts/dist/build/ffitarget.h:157:7: error:
      error: "FFI_TYPE_LAST" is not defined [-Werror=undef]
      #if !(FFI_TYPE_LAST == FFI_PPC_TYPE_LAST  \
 }}}
 and a few more like this.

 Perhaps, we could turn off the warning for files that include `ffi.h` on
 PowerPC.
