* elf64-sparc.c: Add ATTRIBUTE_UNUSED to unused function parameters.

	Remove unusued variables.
	(sparc64_elf_relocate_section): Change r_symndx type to unsigned long.
	(sparc64_elf_merge_private_bfd_data): Fix shared library case from
	previous fix, so that shared libs really don't influence targets
	extension mask and memory model.
