[boost] [thread] auto-link configuration macro

Contrary to what http://www.boost.org/more/getting_started.html#auto-link
makes you think, BOOST_THREAD_DYN_LINK doesn't cause the Boost.Thread
auto-link configuration to choose the DLL version.

Inspecting the config.hpp header in the detail directory, one finds:

#if defined(BOOST_THREAD_BUILD_DLL)   //Build dll
#elif defined(BOOST_THREAD_BUILD_LIB) //Build lib
#elif defined(BOOST_THREAD_USE_DLL)   //Use dll
#elif defined(BOOST_THREAD_USE_LIB)   //Use lib
#else //Use default
(...)

The attached patch "fixes" this behaviour, in a backwards compatible
manner. Is it correct? Am I missing something?
