Khem Raj 1936904ad3 cargo: Mark the cargo-native dependency specific to target
Fixes dependency loop

These are usually caused by circular dependencies and any circular dependency chains found will be printed below. Increase the debug level to see a list of unbuildable tasks.

Identifying dependency loops (this may take a short while)...
