Subject: [PATCH] Avoid exporting symbols more than once.

Exporting `__rust_alloc_error_handler_should_panic` multiple times
causes ld.gold to balk with: `error: version script assignment of  to
symbol __rust_alloc_error_handler_should_panic failed: symbol not
defined`

Specifically this breaks builds on DragonFly and YoctoProject with
ld.gold.  Builds with ld.bfd should be unaffected.
