* sysdeps/i386/tls.h (TLS_DO_MODIFY_LDT): Rewrite asm to use %ebx
optimally conditional on [__PIC__]. (TLS_DO_SET_THREAD_AREA): New macro, implement inline syscall without touching errno, and use latest modify_ldt-like interface. (TLS_SETUP_GS_SEGMENT): Use that instead of INLINE_SYSCALL. * sysdeps/i386/useldt.h (DO_MODIFY_LDT): Set %gs in this macro. (DO_SET_THREAD_AREA): New macro, uses current syscall interface with existing %gs value as the segment to set. (INIT_THREAD_SELF): Rewritten using those. Use set_thread_area only under [HAVE_TLS_SUPPORT] so we can rely on the initialization done by the first thread's early TLS setup.
