powerpc gold, work around pr17670
pr17670 is about an assert triggering on a branch to an undefined weak symbol, the symbol being undefined due to dropping its comdat group section. (Well sort of. The symbol is actually defined in an .opd section which isn't part of the group, but the code section the opd entry points at is dropped.) So don't assert. Also, don't make long branch stubs to such symbols, and arrange to have target-reloc.h code warn when applying relocs that use the sym. PR 17670 * symtab.cc (Symbol::set_undefined): Remove assertion. * powerpc.cc (Target_powerpc::symval_for_branch): Don't assert on symbols defined in discarded sections, instead return false. Rearrange params, update all callers. (Target_powerpc::Branch_info::make_stub): Don't make stubs for branches to syms in discarded sections. (Global_symbol_visitor_opd::operator()): Set discarded opd syms undefined and flag as discarded. (Target_powerpc::Relocate::relocate): Localize variable.
