Add a patch to create /run/user/0 if we're trying to resolve a DIR: ccache somewhere below it and neither the target location nor /run/user/0 exist yet. The better workaround is to set the location's owner to "linger" via logind, since even after we do what we're doing here, if the user logs in and logs back out, our location is still removed.

A hack: if we're looking at creating a ccache directory directly below
|
|
the /run/user/0 directory, and /run/user/0 doesn't exist, try to create
|
|
it, too.
