## Check the values of sh_info fields set by default for
## explicitly listed .dynstr, .dynsym, .strtab and .symtab
## sections.
##
## For symbol table sections, sh_info has a value which is
## one greater than the symbol table index of the last
## local symbol.
##
## sh_info isn't set for string table sections.
