Fix GCC 4.2 warnings like:

cc1: warnings being treated as errors
binutils-gdb/bfd/dwarf2.c:1844: warning: declaration of ‘time’ shadows a global declaration
/usr/include/time.h:187: warning: shadowed declaration is here
binutils-gdb/bfd/dwarf2.c: In function ‘line_info_add_file_name’:
binutils-gdb/bfd/dwarf2.c:1854: warning: declaration of ‘time’ shadows a global declaration
/usr/include/time.h:187: warning: shadowed declaration is here

bfd/

	* dwarf2.c (line_info_add_include_dir_stub): Replace time with
