Bug 226070

I attempted to do a parallel build of guetzli by adding ALLOW_MAKE_JOBS=yes to poudriere.conf and observed this failure:

It looks like it is trying to compile some source files and stash the object files in a directory before creating the directory.  This could be fixed by patching the source Makefile to add the necessary dependencies so that the order of operations is correct, but it is probably easier to add MAKE_JOBS_UNSAFE=yes to the port Makefile to force the build to be single-threaded.
