Creating a bundle fails due to missing 'libhostpolicy.dylib' library on M1 Mac and Windows

File a bug

When using dotnet ef migrations bundle to create a bundle for the linux-x64 runtime, I encounter an exception due to missing the libhostpolicy.dylib library. This same exception happens when running on an M1 Mac or on Windows machine.

Attempted fixes

I tried including a runtimeconfig.json file per this Stack Overflow post - but as you can see in the repro, it doesn't make a difference. I also tried specifying expected outputs via the DatabaseMigrator csproj file per various StackOverflow suggestions; none of them helped.

    <GenerateRuntimeConfigurationFiles>true</GenerateRuntimeConfigurationFiles>
    <InvariantGlobalization>true</InvariantGlobalization>
    <RuntimeIdentifiers>linux-x64,osx.11.0-arm64</RuntimeIdentifiers>
    <RuntimeIdentifier>linux-x64</RuntimeIdentifier>
    <OutputType>EXE</OutputType>

Include your code

I've made a small project to reproduce - https://github.com/evolutionise/minimal-libhostpolicy.dylib-repro. In order to get the same exception, run any of the below commands inside the DatabaseMigrator project directory.

dotnet ef migrations bundle --runtime linux-x64 --verbose dotnet ef migrations bundle --runtime linux-x64 --self-contained --verbose dotnet ef migrations bundle --runtime linux-x64 --framework net6.0 --self-contained --verbose

Include verbose output
