DragonFly 1.13.0-DEVELOPMENT
>Description:
The configure script of lang/python21 has configure check for existance of 
PTHREAD_SCOPE_SYSTEM and it calls pthread_create() with first argument NULL.

While it's somewhat arguable whether it's allowed or not, experience shows that 
at least some OS'es behave unreliable in this case - Linux segfaults and some 
versions of DragonFly BSD hang.
>How-To-Repeat:
Try to build lang/python21 in Linux or DragonFly BSD.
>Fix:
