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.
