We have been initialized by a call to elf_symfile_init, which
currently does nothing.
- SECTION_OFFSETS is a set of offsets to apply to relocate the symbols
- in each section. We simplify it down to a single offset for all
- symbols. FIXME.
-
This function only does the minimum work necessary for letting the
user "name" things symbolically; it does not read the entire symtab.
Instead, it reads the external and static symbols and puts them in partial
dwarf2_free_objfile (objfile);

- It is passed a pointer to a struct sym_fns which contains, among other
- things, the BFD for the file whose symbols are being read, and a slot for
- a pointer to "private data" which we can fill with goodies.
-
- For now at least, we have nothing in particular to do, so this function is
- just a stub. */
