	gdb            : ChangeLog findvar.c symtab.c 

Log message:
	Revert "Search global symbols from the expression's block objfile first."
	
	The search order used in this patch breaks global symbol lookups
	for certain symbols when copy-relocation is used.  A slightly different
	search order will be implemented later.
	
	gdb/ChangeLog:
	
	Revert the following patch:
	* findvar.c (default_read_var_value): For LOC_UNRESOLVED symbols,
	try locating the symbol in the symbol's own objfile first, before
	extending the search to all objfiles.
	* symtab.c (lookup_symbol_aux_objfile): New function, extracted
	out of lookup_symbol_aux_symtabs.
	(lookup_symbol_aux_symtabs): Add new parameter "exclude_objfile".
	Replace extracted-out code by call to lookup_symbol_aux_objfile.
	Do not search EXCLUDE_OBJFILE.
	(lookup_static_symbol_aux): Update call to lookup_symbol_aux_symtabs.
	(lookup_symbol_global): Search for matches in the block's objfile
	first, before searching all other objfiles.
