I don't get why this is needed. The point of calling ldconfig -r is to
create that directory and create the aux-cache file in it. In my tests
ldconfig does create that directory properly when ran with -r.

Even if it ends up that in some conditions yet to be found, the
directory is not created, this doesn't seems correct. This means that
aux-cache file is also not created, which is more problematic.
