Fixes to powerpc64 gold ELFv2 support
* powerpc.cc (Target_powerpc::glink_section): Provide non-const
accessor.
(Target_powerpc::Branch_info::make_stub): Make global entry stubs.
Only call ppc64_local_entry_offset for 64-bit. Restrict
symval_for_branch lookup to ELFv1.
(Stub_table::add_plt_call_entry): Use unsigned int off.
(Output_data_glink::Address, invalid_address): New.
(Output_data_glink::add_eh_frame): Move out of line. Add
support for ELFv2.
(Output_data_glink::add_global_entry, find_global_entry,
global_entry_address): New functions.
(Output_data_glink::global_entry_stubs_, end_branch_table_,
ge_size): New variables.
(Output_data_glink::set_final_data_size): Add global entry
stub sizing.
(Output_data_glink::do_write): Write global entry stubs.
(Target_powerpc::Scan::reloc_needs_plt_for_ifunc): Add target
parameter. Return true for ELFv2. Adjust callers.
(Target_powerpc::Scan::local, global): Restrict opd lookup to
ELFv1. Similarly for ifunc and dynamic relocation processing
specific to ELFv1. Recognize that symbols are defined on
their plt entries for ELFv2.
(Target_powerpc::symval_for_branch): Assert if called for
ELFv2 or ppc32.
(Target_powerpc::Relocate::relocate): Use global entry plt
stub for symbol value if such exists on ELFv2.
(Target_powerpc::Relocate::relocate): Don't call
symval_for_branch when ELFv2. Do adjust for local entry
offset when ELFv2.
(Target_powerpc::do_dynsym_value): Set symbols to global entry
plt stub for ELFv2.
(Target_powerpc::do_plt_address_for_global): Similarly.
