* elf64-sparc.c (sparc64_elf_build_plt): Cosmetic change - ABI
wants ba,a,pt %xcc instead of %icc.
Emit correct .PLT0-(.PLTN+4) initial value into the pointer slots
of large PLT entries.
(sparc64_elf_plt_ptr_offset): Fix calculation.
(sparc64_elf_finish_dynamic_symbol): Negative value of R_SPARC_JMP_SLOT
addend should be relative to load address, not .plt section start.
(sparc64_elf_size_info): Sparc64 uses 32bit .hash entries.
