The architecture should match your target, i.e. arm. (Shouldn't matter though, 
since your cross-debugger doesn't not support i386 anyway.)
Also, have you set the sysroot?
And which version of Creator are you using?

This looks to be the main problem. Again: Have you set the correct sysroot?

Which commands do you send to gdb when manually debugging?

It's an sh script intended for doing preparations on the server side, like 
copying your program or starting gdbserver. See the email you referenced above 
for an example.

How do I know if I'm the intended addressee? Anyway, you are hereby informed 
that I received this message.
