* ELF types, defined in the "enum Elf_Type" API.
*
* The members of the list form a 3-tuple: (name, C-type-suffix, OSversion).
* + `name' is an Elf_Type symbol without the `ELF_T_' prefix.
* + `C-type-suffix' is the suffix for Elf32_ and Elf64_ type names.
* + `version' is the OS version the symbol first appeared in.
*
* OS revisions of note are:
* 600102 - The earliest (6.0-STABLE) version supported by this code.
* 700009 - Symbol versioning and ELF64 type changes.
* 700025 - More ELF types and the introduction of libelf.
