* sysdeps/sparc/sparc32/dl-machine.h (elf_machine_load_address): Don't rely on *r_offset of R_SPARC_RELATIVE reloc in .got to contain the addend. * sysdeps/sparc/sparc64/dl-machine.h (elf_machine_load_address): Use the same l_addr computation. * sysdeps/sparc/sparc64/configure.in: Removed. * sysdeps/sparc/sparc64/configure: Removed. * config.h.in (SPARC64_DYNAMIC_BEFORE_GOT): Remove.
