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. 2020-10-15 Rasmus Villemoes <rv@rasmusvillemoes.dk> 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.
