fd834e57ff 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.)

50701cc170 gold: enable new dtags by default
The "new" dtags options have been around for 14+ years, and for all the
targets that gold supports, these flags have always existed.  So enable
them by default.

Having behavior be different from ld.bfd isn't new, and this behavior
is the "better" one, so there shouldn't be a problem based on that.
