    PPC gold doesn't check for overflow properly
    
    Corrects overflow test for rel14, addr14, rel24, addr24 branch relocs,
    and prints an information message to give a hint as to how a branch
    that can't reach a stub might be cured.
    
    bfd/
    	* elf64-ppc.c (group_sections): Init stub14_group_size from
    	--stub-group-size parameter divided by 1024.
    gold/
    	* powerpc.cc (Stub_control::Stub_control): Init stub14_group_size_
    	from --stub-group-size parameter divided by 1024.
    	(Powerpc_relocate_functions::rela, rela_ua): Add fieldsize
    	template parameter.  Update all uses.
    	(Target_powerpc::Relocate::relocate): Rename has_plt_value to
    	has_stub_value.  Set for long branches.  Don't report overflow for
    	branch to undefined weak symbols.  Print info message on
    	overflowing branch to stub.
