We use `#[global_allocator]` for `stage0` builds of libstd, and also with `feature = "force_alloc_system"` that's set for a local rebuild, where the bootstrap compiler is the same version and otherwise uses the `--cfg stage1`. We only need the unstable `feature(global_allocator)` for a true `stage0` being 1.27. For rebuilds with 1.28, that feature is stable and causes a denied warning if it's enabled, so we should avoid it.

Note that the master branch has removed this feature line altogether, so this patch is only needed on beta. |
