Fix problems with the --dynamic-list option.
PR gold/13577 complains that even though symbols listed in the --dynamic-list script are exported, they are still bound symbolically if -Bsymbolic is also used. There are two underlying problems here. First, -Bsymbolic should be overridden by --dynamic-list, since the dynamic list provides an explicit list of symbols that are not bound within the library, and if we go ahead and set DT_SYMBOLIC, then the dynamic loader will bind it within the library anyway. Second, gold did not properly identify the symbols listed in the file as preemptible. PR gold/16530 complains that symbols listed in the --dynamic-list script can still be garbage collected. I've fixed this by checking the symbols as they're added to the symbol table. (Unlike the --export-dynamic-symbol option, we can't iterate over the list, because the --dynamic-list script can have wildcards in it.) gold/ 2014-02-05 Cary Coutant <ccoutant@google.com> PR gold/13577 * options.cc (General_options::parse_dynamic_list): Set have_dynamic_list_.
