It is my approach for recipe execution guards. I hope that such conditions
are sufficient to let the affected recipes only run for a single target
despite of the specification of several output files there.
Some targets will not usually work together with the make command-line
option "-j" if a corresponding value was passed that is greater than one
for such a parameter.

Thanks for your reminder.
Are there any more programs which support text replacement within content
from "shell variables" directly?
