Lots of error messages when launching emulator debug

Steps to reproduce:

1. Start QtCreator on Windows host
2. Open example project (Examples\B2Qt-5.9\basicsuite\textinput)
3. Configure project to launch on emulator
4. Start debugging

Expected outcome:

• Emulator is started with debuggable application running
• No error prints are printed to the output panes

Actual outcome:

• There are a lot of error prints in the "Application output" pane
• At least following messages trash the log:
  • Warning: ptrace(regsets_store_inferior_registers): Bad address
• These might be ok, but should be checked:
  • Unable to query physical screen size, defaulting to 100 dpi.
  • Could not load shared library symbols for /usr/lib/plugins/generic/libqvinputplugin.so.
