That would be nice but is not trivially doable.
We need to discover when there is a section mismatch
resulting from for example a function in kernel/*
calling a function in arch/$ARCH/kernel so we
need to execute the check on multiple levels
i order to catch the bugs as early as possible.

The easy 'fix' would be to execute the check only
on vmlinux.o (default behaviour) but the added
checks with the option enabled allows us to
be much more precise in reporting where
the section mismatch originate from.
