-DESCRIPTION
+ DESCRIPTION
- Given an open bfd, a base address to relocate symbols to, and a

- or not (may be shared library for example), add all the global
- function and data symbols to the minimal symbol table.

- In stabs-in-ELF, as implemented by Sun, there are some local symbols
- defined in the ELF symbol table, which can be used to locate
- the beginnings of sections from each ".o" file that was linked to
- form the executable objfile. We gather any such info and record it
- in data structures hung off the objfile's private data.
