We figured it out: we had --skip-innodb, which crashed anyone who
didn't have Innodb support built.

Is there any way we could have it add --skip-innodb if and only if
Innodb support is present? I can't find a mysql_* function that
describes server functionality. A compile time option would work as
well I suppose, since we're currently statically linking.
