* elf64-sparc.c (sparc64_elf_relocate_section): Set relocation address
for undefined symbols to be the beginning of the section.
* elf64-sparc.c (sparc64_elf_adjust_dynamic_symbol): Don't allocate
four extra entries at the beginning of the .rela.plt section.
(sparc64_elf_finish_dynamic_symbol): Adjust the offset in the .rela.plt
section to account for the four reserved entries in the .plt section.
