sparc: Use ba,a,pt in PLTs and fix bugs in R_SPARC_JMP_IREL handling.

2010-03-03  David S. Miller  <davem@davemloft.net>

	* sysdeps/sparc/sparc32/dl-machine.h (elf_machine_lazy_rel): Must
	pass '1' for 't' argument to sparc_fixup_plt.
	* sysdeps/sparc/sparc64/dl-machine.h (elf_machine_lazy_rel):
	Likewise.
	* sysdeps/sparc/sparc32/dl-plt.h (OPCODE_BA_PT): Define.
	(sparc_fixup_plt): Document 't' argument.  Enable branch
	optimization and use v9 branches when possible.  Explain why we
	cannot unconditionally patch the branch into the first PLT
	instruction.
	* sysdeps/sparc/sparc64/dl-plt.h (sparc64_fixup_plt): Document 't'
	argument.  Use v9 branches when possible.  Explain why we can in
	fact unconditionally use a branch in the first PLT instruction
	here.
