Hi,everyone,
    I checkout FreeBSD‘s source codes to my /usr/src
    I use command 
    make buildworld 
    int directory /usr/src to build a world.I want to do some debug to lib /usr/src/lib/libthr.If I modified some files in /usr/src/lib/libthr/thread, how could I build libthr except other components of world?
   btw,I execute command 
   make
   in /usr/src/lib/libthr get this :
