add new stage 2b to dynamic linker bootstrap for thread pointer
commit a603a75a72bb469c6be4963ed1b55fabe675fe15 removed attribute const from __errno_location and pthread_self, and the same reasoning forced arch definitions of __pthread_self to use volatile asm, significantly impacting code generation and imposing manual caching of pointers where the impact might be noticable. reorder the thread pointer setup and place it across a strong barrier (symbolic function lookup) so that there is no assumed ordering between the initialization and the accesses to the thread pointer in stage 3.
