As documented in the Admin Guide:

>>>
5.2.3 cn=schema

The cn=schema entry holds all of the schema definitions that are hard-coded in 
slapd. As such, the values in this entry are generated by slapd so no schema 
values need to be provided in the config file. The entry must still be defined 
though, to serve as a base for the user-defined schema to add in underneath. 
Schema entries must have the olcSchemaConfig objectClass.

In other words, just make a blank entry. See the example in 5.2.3.3.
