Maybe you had APC installed when you installed MediaWiki for the first
time? Then it may have suggested you that config.
After that you may have uninstalled APC and merrily continued without
noticing.
I don't think update.php should ignore that setting (and the wiki
would also die anyway). It would be preferable to have a nicer failure
message, though.
