Update.
* pthread_create.c: Define __pthread_keys using nocommon attribute, not by placing it explicitly in bss. Remove DEFINE_DEALLOC definition. Not needed anymore. * allocatestack.c: Define ARCH_MAP_FLAGS if not already defined. Use it in mmap call to allocate stacks. * sysdeps/pthread/createthread.c (create_thread): Fix comment.
