I'm using yaml2obj from head -- maybe there's a recent change that fixed this?

  $ bin/yaml2obj ~/src/llvm/test/tools/llvm-objcopy/reloc-no-symtab.test | bin/llvm-readobj -sections | grep -A 10 .rela.plt
      Name: .rela.plt (16)
      Type: SHT_RELA (0x4)
      Flags [ (0x42)
        SHF_ALLOC (0x2)
        SHF_INFO_LINK (0x40)
      ]
      Address: 0x0
      Offset: 0x240
