implicit-sections.yaml | Explore in Territory

## Check the section header properties of ".dynsym",
## ".dynstr", ".symtab", ".strtab", ".shstrtab".
## These sections sections are usually added implicitly,
## but here we add them explicitly in YAML and verify.
## We check their order matches YAML and that file offset is
## ascending. This is a natural default behavior.
