Most of the go(1) tools will create the missing directory.
Yet, it is better to define this dependency explicitly to make(1),
to avoid unnecessary surprises.
Another useful feature of make(1) is the multiple targets per rule.
This way, we can have the same action and it is the target the variable
of the rule, anymore.
There is a special rule in make(1) to denote that we don't care about
the result of a command. Additionally, we can also instruct rm(1) not
to complain when it didn't find a file/directory to remove.
As a final touch, there is no point of having 2 shell executions to
remove 2 or more files. We can compress these 2 recipes into a single
one.
