1. Stop passing -export-dynamic to wasm-ld. …

   -export-dynamic was a temporary hack added in the early days of the Rust
   wasm32 target when Rust didn't have a way to specify wasm exports in the
   source code. This flag causes all global symbols, and some compiler-internal
   symbols, to be exported, which is often more than needed.
   
   Rust now does have a way to specify exports in the source code:
   `#[export_name = "..."]`.
   
   So as the original comment suggests, -export-dynamic can now be removed,
   allowing users to have smaller binaries and better encapsulation in
   their wasm32-unknown-unknown modules.
   
   It's possible that this change will require existing wasm32-unknown-unknown
   users will to add explicit `#[export_name = "..."]` directives to
   exporrt the symbols that their programs depend on having exported.
