Description
When using a target: directive as a bakefile context in a multi-platform scenario, the platforms of the targets have to match exactly or the build fails.
Expected behaviour
The build should succeed if the referencing target is built for a subset of the platforms of the referenced target.
Actual behaviour
The build fails unless the platforms match exactly.
