It's a completely unrelated issue at the link stage that gets
exposed by fixing the other bug. I don't see this in my
randconfig builds right now, so I probably have a workaround for
it somewhere, but I can't find it.

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?

Thanks Arnd for the info, we will check and avoid wrong bisection
for this. Sorry for the noise.
