Reject zero-sized symbols when creating copy relocations. Copy relocations are relocations to copy data from DSOs to executable's .bss segment at runtime. It doesn't make sense to create such relocations for zero-sized symbols. GNU linkers don't agree with each other. ld rejects such relocation/symbol pair. gold don't reject that but do not create copy relocations as well. I took the former approach because I don't think the latter is what user wants. llvm-svn: 270525
