[Interest] Running qemu as debug service provider in Qt Creator

Thanks, but it doesn't work. The "Attach to Running Server" dialog in Qt
Creator is a bit confusing.

Kit: My gcc-arm-none-abi kit (based upon the arm-none-eabi-gcc-8 toolchain
shipped by the Qt maintenance tool).

Server port: 1234
Local executable: The application ELF file
Break at main is enabled

I get "Unable to create debugging engine". My kit uses arm-none-eabi-gdb-py
as the debugger. The device is a bare metal device and the debug server
provider is set to None. If I choose the arm-none-eabi-gdb executable
instead, I get "Failure during startup. Aborting. No debug server provider
found for".

Does the "attach to running server" even work for cross builds?
