Apparently src/lib/log.c is the only source which uses HAVE_THREAD_TLS,
and from the source I can see that once I disable HAVE_THREAD_TLS, in my 
case, the code will be USE_PTHREAD_FOR_TLS. Sorry this sounds 
like something for the developer folks but it remains as a 
user question:- 

What is the performance impact of disabling THREAD_TLS but
USE_PTHREAD_FOR_TLS instead ?

Thank you for your attention.
