qemu_xtensa cannot be debugged with SDK

[andrewboie]

I ran a test case with "make debugserver".

I then tried to connect to it with GDB:

This is pretty bad, if I am doing new feature development and something only crashes on Xtensa, it will be very difficult to figure out what is going on.

This is a duplicate of #4309. It is an SDK bug and not something we can fix in Zephyr. This has been resolved meanwhile and we are waiting for the fix to be verified.
