Attached is the Makefile that demonstrates the problem.  Run it like this:

	make obj; make all

Then try:

	make install

And then try:

	make -j2 install

Note the difference.  This fixes the problem:

I'm not sure if this a make(1) bug or a feature, as both NetBSD and
OpenBSD behave the same.  But I'm pretty sure this is a bug.  Will?
