Sure, of course.

What I was trying to say was, any rule that would normally be run will
be run regardless of order-only or not, because all the targets in the
makefile are phony.  So adding or removing the order-only operator in a
prerequisites list makes no difference to how the targets will be
processed, in this specific makefile.
