* binfile.c (get_debug_binaries): Keep a list of elf files for
each binary file. In some cases, notably glibc on Fedora, the
debug binary does not contain a symbol table, but the original
file does.

Deal with address offsets. Address lookup is now:

- Then convert to an offset into the text segment
- Then add the load address of the text segment (found in the
debug binary)
- Then finally lookup the result in the symbol table.
