brooks b818dbf010 Be a little more read-only file system friendly when running the Linux
ldconfig.  Build the cache in a temporary directory and only install it
if it's actually different that the installed one.

Also, use "cat tmp > real" to install the temporary file in the real
location to allow the real location to be a symlink to a writable
directory such as /var/run (where the file actually belongs).
