The obvious answer is .. it is mkimage that it is complaining about. You
are packaging mkimage (which is likely an x86 elf file) into your
kernel-dev package (which is your target arch, likely powerpc or ARM). 
Hence the QA error.

In your kernel recipe, you can remove the file before packaging
(i.e. in the do_install_append) or inhibit the QA check for your recipe.

What exactly does your kernel recipe look like ? What is building mkimage
and then getting it installed into /usr/src/kernel ?

My suggestion is to track that down, versus inhibiting the QA check.
