* elf/tls-macros.h (TLS_LD, TLS_GD): Use call insn, not callq.
* sysdeps/unix/x86_64/sysdep.S [USE_TLS && HAVE___THREAD] [! PIC]: Use direct-%fs form of TLS access for errno. * sysdeps/unix/sysv/linux/i386/i686/sysdep.h: File removed, since the i386 version has all the same asm now. * sysdeps/i386/elf/configure.in: Add @GOTNTPOFF and @NTPOFF uses to the TLS support check. * sysdeps/i386/elf/configure: Regenerated. * sysdeps/unix/sysv/linux/i386/sysdep.h [USE_TLS && HAVE___THREAD] (SYSCALL_ERROR_HANDLER): Use direct-%gs form of TLS access for errno. * sysdeps/unix/i386/sysdep.S (syscall_error) [USE_TLS && HAVE___THREAD]: Use TLS access for errno.
