71de341392 V850/BFD: Call `_bfd_elf_copy_private_bfd_data' again
Correct a regression introduced with commit 685080f210 ("Adds support
for generating notes in V850 binaries.") which replaced rather than
extending the call to `_bfd_elf_copy_private_bfd_data' with
`v850_elf_copy_private_bfd_data'.  Consequently ELFOSABI_GNU marking is
not propagated to output by `objcopy' from objects containing
STB_GNU_UNIQUE symbols.

	bfd/
	* elf32-v850.c (v850_elf_copy_notes): New function, factored out
	from...
	(v850_elf_copy_private_bfd_data): ... here.  Call the new
	function and `_bfd_elf_copy_private_bfd_data'.

	binutils/
	* testsuite/binutils-all/objcopy.exp: Don't skip the `strip-10'
	test for the V850.

4ade44b727 Set dynamic tag VMA and size from dynamic section when possible
Rather than searching the output for a specific named section, it's
better, where possible, to use a linker created dynamic section to set
a dynamic tag's value.  That way ld doesn't depend on the output
section name, making it possibile to map dynamic sections differently.

c8e44c6d16 ld -z combreloc elf_link_sort_relocs
A linker script may put .rela.plt in with other .rela.dyn relocs.

1f56df9d0d [AArch64] Also puts value in place for R_AARCH64_RELATIVE
When handling absolute relocations for global symbols bind within the
shared object, AArch64 will generate one dynamic RELATIVE relocation,
but won't apply the value for this absolution relocations at static
linking stage. This is different from AArch64 gold linker and x86-64.

This is not a bug as AArch64 is RELA, there is only guarantee that
relocation addend is placed in the relocation entry.  But some
system softwares originally writen for x86-64 might assume AArch64
bfd linker gets the same behavior as x86-64, then they could take
advantage of this buy skipping those RELATIVE dynamic relocations
if the load address is the same as the static linking address.

This patch makes AArch64 BFD linker applies absolution relocations at
static linking stage for scenario described above.  Meanwhile old AArch64
android loader has a bug (PR19163) which relies on current linker behavior
as a workaround, so the same option --no-apply-dynamic-relocs added.
