* elf64-sparc.c (sparc64_elf_relocate_section): Set relocation address

Browse Source 
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.
