Inhibit support for C++0x threads on VxWorks < 6
As for condition variables, the C++0x threads support relies on
VxWorks entry points not available in VxWorks versions prior to 6.
We just expose absence of support for C++0x threads on such systems.

libgcc/
* config/gthr-vxworks.h: Condition the ___GTHREADS_CXX0X
section on VxWorks >= 6.
* config/gthr-vxworks-thread.c: Condition the entire
implementation on __GTHREAD_CXX0X.
