🐛 Fix C platform output

Previously, setting `output` would make the derivation
end up on the correct component attribute but when splicing happened

 ## Fixed
 - Overriding the factory of a C platform caused the 'override' function
   to disappear from the resulting set.
+- `output` now works as expected on C platforms. Previously, setting
+   output to a different value than `name` created a broken
+   configuration.
