* sysdeps/x86_64/sysdep.h [HAVE_ELF] (L): Define with .L##name form. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (L): Don't define it here. * sysdeps/generic/dl-lookupcfg.h [USE_TLS] (DL_LOOKUP_RETURNS_MAP): Define it, because _dl_sym presumes it (for any platform). * sysdeps/x86_64/dl-tls.h: New file. * sysdeps/x86_64/dl-machine.h (elf_machine_rela): Add a cast. * sysdeps/x86_64/elf/configure.in: New file. * sysdeps/x86_64/elf/configure: New generated file.
