Some targets are only really, or at least regularly, regression-tested
in a crossed configuration. Currently we only have native compiled test
cases for the STB_GNU_UNIQUE feature in the linker test suite. This is
nice, covering run-time semantics even, but quite often not run at all.
Consequently a regression may remain unnoticed for long.
Add a simple test case then to provide basic linker coverage with no
need for a compiler or a native toolchain.

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.
