It's worth noting that the current behavior implied whole archive for all libraries passed, right? So this could regress code in theory? It seems OK to have the more limited and arguably correct behavior, though. @bors r+ |

…lacrum linker: Avoid library duplication with `/WHOLEARCHIVE` Looks like in rust-lang#72785 I misinterpreted how the `link.exe`'s `/WHOLEARCHIVE` flag works. It's not necessary to write `mylib /WHOLEARCHIVE:mylib` to mark `mylib` as whole archive, `/WHOLEARCHIVE:mylib` alone is enough. https://docs.microsoft.com/en-us/cpp/build/reference/wholearchive-include-all-library-object-files?view=msvc-160
