The llama.cpp project released version b10798, introducing a change to make the build information output stream configurable. This update allows `llama_print_build_info` to write to a caller-provided FILE* instead of hardcoding stderr.
- The parameter defaults to stderr so existing callers keep their current behavior.
- The version command in llama-app now passes stdout, ensuring plain version output goes to the expected location.
This change improves flexibility for developers who need to redirect build information output programmatically.
