	* elf/dl-addr.c (_dl_addr): Add a cast.

	* sysdeps/x86_64/dl-machine.h (elf_machine_rela) [USE_TLS]: Handle new
	TLS relocs R_X86_64_DTPMOD64, R_X86_64_DTPOFF64, and R_X86_64_TPOFF64.

	* elf/elf.h (R_X86_64_DTPMOD64, R_X86_64_DTPOFF64, R_X86_64_TPOFF64,
	R_X86_64_TLSGD, R_X86_64_TLSLD, R_X86_64_DTPOFF32,
	R_x86_64_GOTTPOFF, R_X86_64_TPOFF32): New macros.
	(R_X86_64_NUM): Update the value.
