If we have to provide the location, we have to ensure the 
directory exists. I guess it is not necessarily an issue, but I 
figured that if the semantic of nil as last argument of 
`comp--native-compile' and the underlying mechanism of temporary 
files is already there, and is supposed to stay, we might as well 
use it.

The current meaning of `inhibit-automatic-native-compilation' is a 
current "good" state that allowed a large number of build failures 
to disappear, and it would be reassuring to be able to reproduce 
that state exactly, before eventually migrating to providing the 
location ourselves, if we see that we can do so without errors.
