armv7m7-imxrt117x-evk: system occasionally freezes while exiting spawned psh

[damianloew]

• it occurs after executing some of psh tests (for example gibber, auth)
• discovered both on CI and locally
• phrtos-project rev: https://github.com/phoenix-rtos/phoenix-rtos-project/commits/master

On ea760a2 still occurs, but the behavior is a bit different:

(psh)% dmesg -D
(psh)% sysexec psh
(psh)% exit
(psh)% dmesg -E
(psh)% 
(psh)% ps

(psh)% 
(psh)% dmesg -D

As it is presented freeze happens while executing one of the next commands

@damianloew Have you tried with the fix in the toolchain build process that was recently merged?

Yeah, it was the reason why it was failing, with a newer toolchain the issue no longer occur, checked on ea760a2

Probably fixed in phoenix-rtos/phoenix-rtos-build@072b859 (toolchain rebuild needed)
