tests/kernel/threads/thread_api: "Double faults" when running code coverage in qemu_x86

[cinlyooi-intel]

To Reproduce
Steps to reproduce the behavior:

# To generate the errors
scripts/sanitycheck --coverage 
   --coverage-platform mps2_an385 -p mps2_an385 
   --coverage-platform qemu_x86 -p qemu_x86  
   --coverage-platform qemu_x86_nommu  -p qemu_x86_nommu -
   -gcov-tool /opt/zephyr-sdk-0.10.0/i586-zephyr-elf/bin/i586-zephyr-elf-gcov \
   -T tests/kernel -T tests/subsys/logging | tee output.log

# the file to open is
# sanity-out/qemu_x86/tests/kernel/threads/thread_apis/kernel.threads/handler.log
