780 sh_link and sh_info fields in stripped section headers, we also
781 check if the sh_type, sh_flags, sh_addralign and sh_entsize
782 fields of the output section match the output. Since
783 --only-keep-debug turns all non-debug sections into SHT_NOBITS
784 sections, the output SHT_NOBITS type matches any input type.
