AArch64: Fix LD crash on weak and undefined TLS symbols. (PR/24602). This patch fixes a few linker crashes due to TLS code reaching an assert when it shouldn't. The first scenario is with weak TLS symbols that remain weak during linking. In this case the mid-end would not have seen a TLS symbol and so wouldn't have allocated the TLS section. We currently assert here and the linker crashes with a not very useful message. This patch changes this to return the value 0 for the TLS symbol in question emulating what lld and gold and other BFD targets do. However because weak TLS is implementation defined and we don't define any behavior for it I also emit a warning to the user to inform them of such. Secondly when a strong TLS reference is undefined. The linker crashes even after it correctly reported that there is an undefined reference. This changes it so that it gracefully exits and reports a useful error. bfd/ChangeLog: PR ld/24601 * elfnn-aarch64.c (aarch64_relocate): Handle weak TLS and undefined TLS.
