Is it possible to get dotnet build to produce a Windows and a Linux executable?

### Is your feature request related to a problem? Please describe.

`dotnet build` on Windows for an executable project will produce a `.dll` and a runnable `.exe` file
`dotnet build` on GNU+Linux for an executable project will produce a `.dll` and a runnable ELF file

There does not seem to be a way to do both.

### Describe the solution you'd like

In our CI/CD build, we would like to produce both the EXE and ELF file. This would make our package runnable on both OS.
Can we have an option to produce both the EXE and ELF file?
Something like: `dotnet build --exe-and-elf`
