[PATCH] Do not fail build if mkimage is not available

[Michael Buesch <mb@bu3sch.de>]

This fixes the boot image wrapper script to not fail the kernel
build if mkimage is not available.
As some distributions don't ship the mkimage program and I am not
interested in uboot images anyway, I don't want to fail the whole kernel
build process because of this unneeded dependency.

Simply drop an error message, but don't fail the build.
