message: Conflict-proof #[global_allocator] symbols too.
  The #[global_allocator] used by relibc is only relibc's business.
  Symbols should therefore not leak if another applications for example
  wants to override the system allocator (and for bootstrap, which links
  to relibc but uses its own #[global_allocator] based on libc functions).
