rustc: Move local native libs back in link-args With linkers on unix systems, libraries on the right of the command line are used to resolve symbols in those on the left of the command line. This means that arguments must have a right-to-left dependency chain (things on the left depend on things on the right). This is currently done by ordering the linker arguments as 1. Local object 2. Local native libraries 3. Upstream rust libraries 4. Upstream native libraries This commit swaps the order of 2 and 3 so upstream rust libraries have access to local native libraries. It has been seen that some upstream crates don't specify the library that they link to because the name varies per platform (e.g. lua/glfw/etc). This commit enables building these libraries by allowing the upstream rust crate to have access to local native libraries. I believe that the failure mode for this scheme is when an upstream rust crate depends on a symbol in an upstream library which is then redefined in a local library. This failure mode is incredibly uncommon, and the failure mode also varies per platform (OSX behaves differently), so I believe that a change like this is fine to make.

rustc: Swap link order of native libs/rust deps This commit swaps the order of linking local native libraries and upstream native libraries on the linker command line. Detail of bugs this can cause can be found in #28595, and this change also invalidates the test case that was added for #12446 which is now considered a bug because the downstream dependency would need to declare that it depends on the native library somehow.
