My commit 261980de18b added alignment for the resource table symbol.
But it is wrong. The Linux remoteproc driver loads and interprets the
contents of the .resource_table ELF section, not of a table symbol.
Without this patch, if the linker happens to output padding for symbol
alignment, then the resource table contents as viewed by the kernel
loader would "shift" and look corrupted.
ld/ChangeLog:
* scripttempl/pru.sc (.resource_table): Align the output
section, not the first symbol.

[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.

[GOLD] Output_data_got tidy
Some Output_data_got methods already have support for addends, but
were implemented as separate methods. This removes unnecessary code
duplication.
Relobj::local_has_got_offset and others there get a similar treatment.
Comments are removed since it should be obvious without a comment, and
the existing comments are not precisely what the code does. For
example, a local_has_got_offset call without an addend does not return
whether the local symbol has *a* GOT offset of type GOT_TYPE, it
returns whether there is a GOT entry of type GOT_TYPE for the symbol
with addend of zero.

[GOLD] Remove addend from Local_got_entry_key
This patch removes the addend from Local_got_entry_key, which is
unnecessary now that Got_offset_list has an addend. Note that it
might be advantageous to keep the addend in Local_got_entry_key when
linking objects containing a large number of section_sym+addend@got
relocations. I opted to save some memory by removing the field but
left the class there in case we might need to restore {sym,addend}
lookup. That's also why this change is split out from the
Got_offset_list change.

After commit 985e0264516 copy_archive function began to pass invalid

timestamps in ar archives. This happens because the bfd_stat_arch_elt

and the whole st_atim timespec untouched leaving them uninitialized
