Introduce a property to influence output location.
Introduce a property to influence output location.

It's useful in certain contexts to have Maven direct outputs to
a non-standard location. By using this property, we can allow
for this, while maintaining the default behavior when this property
isn't used. This behavior is applied to the base configuration
so it can be used in any profile.

The derivation for the default value comes from
http://maven.apache.org/pom.html line 32 of the main POM.
