So we print exact instructions how to get more info.
And several people has posted list of section mismatch warnings recently,
so the instructions are understood.
I fail to see any problem with that.

Obviously it would be better if we bailed out with a big fat warning
if someone _adds_ a new section mismatch warning.

If you by "not offered" try to say that the CONFIG option
is not available in kconfig then you are correct.
But you are in the instructions above asked to supply it
on the command line to make - not to enable it in the
kconfig configuration.

I would prefer we were down to less than 5 warnings so we could
enable it in kconfig but maybe after next merge window.
