The Debian package of ITK 3.18 had issues building in parallel and the
packaging script was set up to filter out that option.

Now that I build only bare ITK 4  without any docs or wrappings it works fine.

However, the wrapitk which is supposed to replace the previous
wrappings gives wildly different logs when built sequentially and in
parallel (although it does not build in either case currently).

Still the parallel build fails much earlier. Log excerpt below.

Thanks
