- Introduced a new method `apply_default_string` to streamline the application of default values for string fields in build flags. - Enhanced `apply_flags_table` to utilize the new method for setting various build flags, improving code readability and maintainability. - Added support for additional build flags: `fuse_ld`, `ranlib`, `strip`, `nm`, `objcopy`, `objdump`, and `readelf`. - Implemented a new command `set` to manage tool aliases for compilers, linkers, and shells, allowing users to set preferred tools in the build environment. - Improved error handling and validation for tool alias configuration, ensuring that existing non-symlink files are not replaced. - Added tests to verify the correct behavior of tool alias management and build flag application.
