I've been thinking harder about this, these files get unlinked at the 
end if they are temporary.
Is there no way to get make to communicate back this info so lto-wrapper 
can just unlink the file on its own? It feels easier and less invasive 
than introducing a whole new option to the driver for only that purpose. 
If there is some way, I'm not aware of it.
