ld/aarch64: xfail non-PIC shared object tests on aarch64
aarch64 does not support building non-PIC shared objects, so mark
tests for these as xfail.

commit eea6dad2b3ae91189caa91145dd133bae0398d21

Similarly to the AArch64 patch, set DF_STATIC_TLS for consistency with
other architectures when we emit IE relocs in a shared library.
* elf32-arm.c (elf32_arm_check_relocs): Set DF_STATIC_TLS when
emitting initial-exec relocs when not linking an executable.

* Tue Jun 24 2014 Kyle McMartin <kyle@redhat.com> - 2.24-16
- Backport a couple LTO testsuite fixes from HEAD.
Default to -ffat-lto-objects for some ld tests, which was the default in
gcc 4.8, but changed in 4.9, and resulted in some failures.
- Add STATIC_TLS flag on ARM when IE relocs are emitted in a shared
library. Also fix up offsets in the testsuite resulting from the
addition of the flags.
- XFail some ld tests on AArch64 to cut some of the spurious testsuite
failures down.
* Sat Jun 07 2014 Fedora Release Engineering <rel-eng@lists.fedoraproject.org> - 2.24-15
- Rebuilt for https://fedoraproject.org/wiki/Fedora_21_Mass_Rebuild
