Worked on modularizing the build system for the CTSRD-CHERI/cheribsd repository by refactoring suffix-transformation rules into a dedicated Makefile include, bsd.suffixes-extra.mk. This approach improved the maintainability and extensibility of the build configuration without altering the existing build output or behavior. The work focused on clear separation of transformation logic, laying a foundation for future enhancements to the build process. Utilizing Makefile and build system configuration skills, the developer ensured that the refactor preserved all functional aspects while making the codebase easier to manage and extend. No bugs were addressed during this period, with efforts concentrated on feature development.
