Expected behaviour

check should have pass

Actual behaviour

Additional context

I actually failed to build current master c68340350c78eea402c4a85f8d9c1b7d3d607635 and then run git bisect python x.py check to find first commit that fails to build.

I also tried clear install of Win10 on virtual machine with only python, Visual Studio Build tools and it failed with same error.

Start by reproducing python x.py check on Windows 10 at the reported commit, then inspect compiler/rustc_codegen_gcc/src/lib.rs and the bootstrap configuration in bootstrap.toml around the duplicate object rmeta candidates. Compare the bisected commit with its predecessor; done means the Windows check completes without the E0464 multiple-candidates error.
