Joel Brobecker 38947ccadc [mach-o] get rid of current_oso global
This current_oso global was used to store the OSO's symbol table
in order to relocate common symbols.  But it is also making the
assumption that all sections are going to be immediately relocated
as macho_add_oso_symfile does:
  - Initialize the current_oso
  - Use it through symbol_file_add_from_bfd
  - Reset the current_oso (to all fields NULL)

What actually happens is that the .debug_frame section gets read
lazily, and thus relocated at a later time.  This relocation causes
current_oso.symbol_table to be initialized (see macho_symfile_relocate)
again.  And this eventually causes to trip the...

        gdb_assert (current_oso.symbol_table == NULL);

...assertion to fail because the symbol_table was never free'ed.
To be complete, this happens because macho_symfile_relocate was
called outside of macho_add_oso_symfile's control, where the
set-global/use/unset-global dance happens.

But it looks like keeping this global around is not necessary, as
this symbol table is only used to relocate the common symbols.
We can do that prior to relocating the rest of the symbols.

gdb/ChangeLog:

        * machoread.c (struct macho_oso_data): Delete.
        (current_oso): Delete.
        (macho_relocate_common_syms): New function, mostly extracted
        out of
        (macho_add_oso_symfile): Call macho_relocate_common_syms.
        Remove code that sets and unset current_oso.
        (macho_symfile_relocate): Delete handling of common symbols,
        now moved to macho_relocate_common_syms.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
