MinGW pthreads miss some features that LLVM uses, and thus cannot be
used.  To fix, remove the pthreads-w32-2.8.0-mingw32-dll package from
your MinGW installation.  E.g. these files:

$MINGWROOT/mingw32
$MINGWROOT/mingw32/include
$MINGWROOT/mingw32/lib
$MINGWROOT/mingw32/include/pthread.h
$MINGWROOT/mingw32/include/sched.h
$MINGWROOT/mingw32/include/semaphore.h
$MINGWROOT/mingw32/lib/libpthread.a

Then reconfigure and recompile everything from scratch.
