Makefile template: Unify calls to the code generator.
Makefile template: Unify calls to the code generator.

This commit makes all arguments to the code generator explicit and alphabetises
them. This should have no effect on current executions, but a future cache
extension uses the arguments and their order to cache executions. By
consistently ordering the arguments and making all parameters explicit, we get
the maximum benefit from this caching process.
