Declare RTS-private prototypes with __attribute__((visibility("hidden")))
This has no effect with static libraries, but when the RTS is in a
shared library it does two things:
- it prevents the function from being exposed by the shared library
- internal calls to the function can use the faster non-PLT calls,
because the function cannot be overriden at link time.
