BTW: i found this false positive had been reported multiple times in history,
in your previous reply [0], you had mentioned below to add a Kconfig dependency,
is it the workaround you refer to?

I had a look at this bug, and found that this is not caused by my commit, but
rather is the result of CONFIG_CPU_BIG_ENDIAN with BE8 format being
incompatible with CONFIG_DEBUG_INFO_BTF.
I'm sure there is an easy fix but I have not found it. Should we just
add a Kconfig
dependency to prevent this, or does anyone have an idea for a proper fix?
