    New pthread_barrier algorithm to fulfill barrier destruction requirements.

building glibc for pre-v9 32-bit SPARC has been broken because 
sysdeps/sparc/sparc32/pthread_barrier_wait.c just contains a #error.

Is this something that is still intended to be fixed?  Or should pre-v9 
32-bit SPARC be considered like the original i386, i.e. too little atomic 
operation support so should no longer be supported with v9 being made the 
official minimum supported by glibc?
