That didn't work too well here.  While it did correctly detect some
instances:

zImage size (8008200) disagrees with linked size (8008192)

it also misdetected others:

zImage size (13348808) disagrees with linked size (-928003328)

It seems to suggest that _magic_end - _magic_start = 0xc8afcb00.
zImage size is 0xcbafc8.  That points at the addresses output by
"nm" being dependent on the endian-ness of the image, which to
me seems utterly insane.

I wouldn't be surprised if that is toolchain version dependent
as well.

IMHO, our toolchain is a mess!
