dnlib Linux R2R mixed dll can't be saved.

If you try to save a R2R linux mixed module dnlib run on an exception. dnlib.DotNet.Writer.ModuleWriterException: Invalid section RVA

The module is published with: dotnet publish -c Release -r linux-x64 -p:PublishReadyToRun=true R2R.ZIP

R2R was never supported. Can you just save it as a normal .NET assembly without any native code (I assume the metadata and original IL code is still in the file).

Maybe with this little test dll would work, but I tryed more complex module and it stoped running on linux. Only way I was able to make it work if I did the following:

1.) Use "crossgen2.exe --compile-no-methods --targetos:windows" to strip native code and convert it to windows PE. 2.) Save module (because it is a windows PE still mixed assembly) 3.) Use "crossgen2.exe --compile-no-methods --targetos:linux" to convert it back to linux PE
