Specify runtime-file for appimagetool

[tamasmeszaros]

Is it possible somehow to specify the --runtime-file (or any other) parameter for appimagetool invocation? I'm trying to create an AppImage for raspberry from the cross compiled artifacts on an x86_64 machine. pkg2appimage respects the ARCH environment variable but at the end the resulting AppImage is still not in ARM format, only the inside data like the AppRun executable.

According to https://github.com/AppImage/pkg2appimage/blob/04166f66368d545764cddf387cb6fd089f323100/pkg2appimage#L487
the updateinformation argument can be abused to pass the --runtime-file argument as well, but is there a better way?

Maybe this should even be done automatically?

I don't think it is implemented. To create AppImages for ARM using this tool, best run pkg2appimage on ARM (or in QEMU).
