* 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.
