[GOLD] Got_entry::write addends
This takes care of writing out GOT entries with addends. The local
symbol case was already largely handled, except for passing the addend
to tls_offset_for_local which might need the addend in a
local_got_offset call. That's needed also in tls_offset_for_global.
I'm assuming here that GOT entries for function symbols won't ever
have addends, and in particular that a GOT entry referencing PLT call
stub code won't want an offset into the code.
PR 28192
* output.cc (Output_data_got::Got_entry::write): Include addend
in global symbol value. Pass addend to tls_offset_for_*.
* powerpc.cc (Target_powerpc::do_tls_offset_for_local): Handle addend.
(Target_powerpc::do_tls_offset_for_global): Likewise.
* s390.cc (Target_s390::do_tls_offset_for_local): Likewise.
(Target_s390::do_tls_offset_for_global): Likewise.
* target.h (Target::tls_offset_for_local): Add addend param.
(Target::tls_offset_for_global): Likewise.
(Target::do_tls_offset_for_local): Likewise.
(Target::do_tls_offset_for_global): Likewise.
