Targets which are presented to the user must be defined regardless of
whether they have any effect. So for instance `install-exec' must
Writing a document describing what we produce is on the to-do list.
It is everything the GNU standards want, but there is more that we
provide that they do not (eg, install-man).

If it is a dependency then it won't work properly with a parallel
make. That's because the -hook for must be run after all the other

Anyone who relies on the ordering has a broken Makefile. If order
matters you must either have an explicit dependency or you must
reinvoke make. If your patch changes only dependency orderings then
it will only affect Makefiles which are already buggy.
