Emit these symbols as long as we're building in a static configuration,
even if we're emitting a dynamic symbol table. This is consistent with
both bfd and gold.
Ordinarily, the combination of -static and -export-dynamic wouldn't make
much sense. Unfortunately, cmake versions prior to 3.4 forcefully
injected -rdynamic [1], so it seems worthwhile to support.
