Modified files:
	gdb            : symfile.c 

Log message:
	Add support for executables whose debug info has been separated
	out into a separate file, leaving only a link behind.
	* objfiles.h (struct objfile): New fields: separate_debug_objfile
	and separate_debug_objfile_backlink.
	(put_objfile_before): New declaration.
	* symfile.c (symbol_file_add_with_addrs_or_offsets): If this
	objfile has its debug info in a separate file, read that,
	too. Save the addrs argument, so we can use it again to read the
	separated debug info; syms_from_objfile modifies the table we pass
	it.
	(reread_symbols): After re-reading an objfile, call
	reread_separate_symbols to refresh its separate debug info
	objfile, if it has one.
	(reread_separate_symbols, find_separate_debug_file,
	get_debug_link_info, separate_debug_file_exists): New functions.
	(debug_file_directory): New global var.
	(_initialize_symfile): Initialize debug_file_directory, and
	provide the new `set debug-file-directory' command to let the user
	change it.
	* objfiles.c (free_objfile): If this objfile has its debug info in
	a separate objfile, free that one too.  If this is itself a
	separate debug info objfile, clear our parent's backlink.
	(put_objfile_before): New function.
	* utils.c (calc_crc32): New function.
	* defs.h (calc_crc32): New declaration.
	* configure.in: Handle --with-separate-debug-dir config option.
	* acinclude.m4 (AC_DEFINE_DIR): New macro.
	* acconfig.h (DEBUGDIR): New macro.
	* configure, aclocal.m4, config.in: Regenerated.
