Thanks for hint. In .rela.debug_pubnames section, I see:

Offset       Info         Type        Sym. Value     Sym. Name + Addend
000000000006 00060000000a R_X86_64_32 0000000000000000 .debug_info + 0

That is clear for me, the assembler used a R_X86_64_32 relocation type.
But .rel / .rela sections are generated by assembler not by C compiler
(gcc -g3 -S test.c), so I still don't know why the assembler used
relocation (and this type of relocation) for directive ".long
.Ldebug_info0" in section .debug_pubnames. This is not the default
behavior for translation of ".long label" directives.
