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.
