[#5588] - Upgrade from 4.1.0 to 4.2.1 fails due to validation error

I'm on Debian 6.0 Squeeze Tomcat6 (6.0.28). I had an issue when upgrading. I don't have any foodmart or sugarcrm installed but the validation is testing for these installations anyway.

Error:
[advanced-sql] 1 of 1 SQL statements executed successfully
[echo] Connection OK
[echo] Validating FoodMart database connection at jdbc:mysql://localhost:3306/foodmart?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&autoReconnectForPools=true. Phase: [test]

I have solved this issue by commenting out line 494 and 495 in buildomatic/bin/validation.xml

E.g.:
<!-- <validateDB systemName="foodmart" phase="test" />
<validateDB systemName="sugarcrm" phase="test" /> -->

I suggest to put this into the documentation.
