ld: Add --export-dynamic-symbol and --export-dynamic-symbol-list
--export-dynamic-symbol-list is like a dynamic list, but without
the symbolic property for unspecified symbols.
When creating an executable, --export-dynamic-symbol-list is treated
like --dynamic-list.
When creating a shared library, it is treated like --dynamic-list if
-Bsymbolic or --dynamic-list are used, otherwise, it is ignored, so
that references to matched symbols will not be bound to the definitions
within the shared library.
PR ld/25910
* NEWS: Mention --export-dynamic-symbol[-list].

lang_append_dynamic_list.
* ldlang.c (current_dynamic_list_p): New.
(ang_append_dynamic_list): Updated to take a pointer to
struct bfd_elf_dynamic_list * argument instead of using
link_info.dynamic_list.
(lang_append_dynamic_list_cpp_typeinfo): Pass
&link_info.dynamic_list to ang_append_dynamic_list.
(lang_append_dynamic_list_cpp_new): Likewise.
