Good question. Not due to llvm-objdump, it is due to the fact AIX does not support bpf (yet).
You should be able to see what is wrong on Linux with following triple as well.

  $ llc -mtriple=bpfel-ibm-aix -filetype=obj -o - llvm-project/llvm/test/CodeGen/BPF/BTF/binary-format.ll
  <unknown>:0: error: Undefined temporary symbol 

The failure are:

  <unknown>:0: error: Undefined temporary symbol 
  ..bin/llvm-readelf: error: '<stdin>': The file was not recognized as a valid object file
  FileCheck error: '<stdin>' is empty.
  FileCheck command line:  .../bin/FileCheck -check-prefixes=CHECK,CHECK-EL .../lvm/test/CodeGen/BPF/BTF/binary-format.ll
