Thanks for your suggestion. One correction and further observation follows:
sh_info points to .debug_info and sh_link is pointing to .dynsym,
not .symtab. This is expected outcome in a ET_DYN file.
However, the bfd/elf.c code shown below does not handle relocations
/* If this reloc section does not use the main symbol table we
don't treat it as a reloc section. BFD can't adequately
represent such a section, so at least for now, we don't
try. We just present it as a normal section. We also
can't use it as a reloc section if it points to the null
section, an invalid section, or another reloc section. */
