The update doesn't modify your LocalSettings.php (much less to a
config that will break the update!).
Looking at the code, in 1.15 a setting of CACHE_ACCEL was silently
ignored if there was no accelerator cache available.
Since the r83140 rewrite (available on mediawiki 1.18), it throws an
exception on such case (it is, after all, a conflictive configuration).
