zephyr: west build for zephyr/samples/net/sockets/echo_server/ on qemu_xtensa target outputs elf with panic

Describe the bug I am trying to get zephyr network examples to run under qemu_xtensa target - west outputs the elfs, however when trying to run them on qemu with west build -t run they generate the following panic: `-- west build: running target run
[0/1] To exit from QEMU enter: ‘CTRL+a, x’[QEMU] CPU: sample_controller

To Reproduce Steps to reproduce the behavior:

1. Have zephyr-sdk and esp-idf installed;
2. build any network example with qemu_xtensa target
3. attempt to run with qemu
4. See panic

Expected behavior It would be expected that the qemu_xtensa elf would run exactly like the qemu_x86 one for these examples.

Impact This bug is a showstopper for my efforts.
