MINOR: threads: Prepare makefile to link with pthread
USE_THREAD option has been added to enable the compilation with the experimental
support of threads . Of course for now, there is nothing. And for a while,
HAProxy will be unstable. When we will be confident enough, this option will be
removed.
For this implementation and probably for a while, only the pthread library will
be supported.
