That's 2 out of 4; I still need to know a symbol which will be present
in libmysqlclient, and which libraries libmysqlclient might depend
upon.

I'll take a guess at mysql_query() being defined in libmysqlclient (it
is referenced in db/drivers/mysql, but doesn't appear to be defined
anywhere), and I'll assume that no other libraries need to be
specified.
