From: Ming Liu <peter.x....@external.atlascopco.com>
The code logic in image-mklibs.bbclass and image-prelink.bbclass is all
about optimizing the rootfs image, so it makes more sense to put them
into IMAGE_CLASSES rather than USER_CLASSES.
What's more, this fixes a potential issue by moving out image-mklibs
from INHERIT, considering that, I found a following dependency is
missing in image-mklibs.bblcass:
...
do_rootfs[depends] +=
"virtual/${MLPREFIX}${TARGET_PREFIX}binutils:do_populate_sysroot"
...
but if I add it in, I got a following error:
...

this can be fixed by moving image-mklibs to IMAGE_CLASSES per test.
Also change the image_types_uboot example in local.conf.sample.extended
to be appended to IMAGE_CLASSES, since now IMAGE_CLASSES has a default
value in local.conf.sample.
