[Mono-list] New: cross-compiling with mkbundle

Hi Miguel,

I have 2 questions about the new mkbundle:

1) Will the new cross-platform mode support embedding the machine config? 

My program uses web connections which relies on the configuration in
machine.config, however when I bundle a program with:

mkbundle --cross {target} --machine-config {path-to-machine.config} ....
app.exe app-native

and then try to run the output, I get the following error:

Unknown stream on embedded package: machineconfig:

2) Cross-compiling for macOS from Linux produces an ELF binary, rather than
a Mac binary (Mach-0?).

Is this happening because I haven't specified a runtime, just a
cross-compilation target?
