* target-reloc.h (scan_relocs): Call scan.local for relocs
against symbols in discarded sections. Pass is_discarded
param.
* arm.cc, * i386.cc, * sparc.cc, * x86_64.cc (Target_*::Scan::local):
Add is_discarded param.
* powerpc (Target_powerpc::Scan::local): Likewise. Use
is_discarded to flag opd entry as discarded. Don't emit dyn
relocs on such entries.
(Target_powerpc::Scan::global): Similarly detect and handle
such opd entries.
(Powerpc_relobj): Replace opd_ent_shndx_ and opd_ent_off_ with
opd_ent_. Update all uses.
(Powerpc_relobj::get_opd_discard, set_opd_discard): New functions.
(Target_powerpc::relocate_section): Zero out discarded opd
entry relocs.
