[boost] [thread] Patch for boost/config/platform/hpux.hpp

Hi, On HP-UX for toolset *acc*(aCC 6.13) Boost.Threads fails to build without the hardcoded *-mt* flag in RC_1_34_0/tools/build/v2/tools/acc.jam for following actions: 1.acc.link bind NEEDLIBS 2.acc.link.dll bind NEEDLIBS 3.acc.compile.c 4.acc.compile.c++ Below mentioned patch defines the macro "BOOST_HAS_THREADS" in boost/config/platform/hpux.hpp for toolset *acc* and does away with the necessity of having to hardcode *-mt* flag. ---------------------------------------------------------------------------- 38a39

# define BOOST_HAS_THREADS
