 903 WARNING: Threading not supported on your platform
 904
 905         You are compiling LXC for bionic target which lacks certain threading related functionality used by LXC API (like pthread_atfork).
 906         Please note that, because of the missing functionality, multithreaded usage of LXC API cause some problems.
