I have two more small patches for complex type support to make it a
bit easier to use.

The first patch makes sure that FFI_TYPE_COMPLEX is only defined
on a system that has complex support in libffi, so the user can
say something like

  #ifdef FFI_TARGET_HAS_COMPLEX_TYPE
    /* (code with complex support) */
  #else
    /* (code without complex support) */
  #endif

The macro FFI_TARGET_HAS_COMPLEX_TYPE is for internal use only.
Once all targets implement complex type support it could be
removed.
