If building libgit2's test suite with tracing disabled, then the compiler will emit a warning due to the unused `message_prefix` function. Fix the issue by wrapping the whole file into ifdef's for `GIT_TRACE` and providing separate empty function implementations for both `cl_global_trace_register` and `cl_global_trace_disable`.
