Subject: stackinit unit test failures on m68k

Hi Geert,

I see the following stackinit unit test failures on m68k when running
the q800 emulation.

    # test_char_array_zero: ASSERTION FAILED at lib/stackinit_kunit.c:333
    Expected stackinit_range_contains(fill_start, fill_size, target_start, target_size) to be true, but is false
stack fill missed target!? (fill 16 wide, target offset by -12)

    # test_char_array_none: ASSERTION FAILED at lib/stackinit_kunit.c:343
    Expected stackinit_range_contains(fill_start, fill_size, target_start, target_size) to be true, but is false
stack fill missed target!? (fill 16 wide, target offset by -12)

Do you happen to know if this a problem with the test, with m68k, or maybe
with the configuration ? My configuration is based on mac_defconfig with
various test options enabled. I use gcc 11.4 to build the image. I tried
with qemu v8.1 and v8.2.

Thanks,
Guenter
