[PATCH] validation: Check stack of interrupted context

[Sebastian Huber]

Hello Kinsey,

I added a test case for

https://devel.rtems.org/ticket/4955

which started as a sparc-specific bug. The test case should also work on 
aarch64. In uniprocessor configurations, it is fine:

qemu-system-aarch64 -no-reboot -nographic -serial mon:stdio -machine 
xlnx-zcu102 -m 4096 -kernel 
build/aarch64/xilinx_zynqmp_lp64_qemu/testsuites/validation/ts-validation-intr.exe

I don't know the architecture good enough to debug this test case. It 
would be good if you could have a look at it since this crash could 
indicate a generic bug in the SMP startup.
