I am afraid it is not the issue of IMAGE_INSTALL

As doc said:
http://www.yoctoproject.org/docs/1.5/ref-manual/ref-manual.html#var-IMAGE_INSTALL
Variable IMAGE_INSTALL is used to specify the packages to install into 
an image.

While adding some packages to image ,the rpm based do_rootfs
failed with '*** not found in the base feeds'

The failure was caused by two kinds of situations:
1. Package does not exist (such as python3), but provided
    by other package (such as python-core), the rpm based
    do_rootfs could not search its provider. And the deb/
    ipk based do_rootfs worked well, it is a defect, and
    I have fixed it (patch sent to community, YOCTO 6918);

2. Package does not exist, and no other package provides it,
    the package installation will fail in any type do_rootfs. We
    met this issue when we set IMAGE_INSTALL = "recipe_name",
    but we don't have the package with that name.

I think what I do is to fix the situation 2.

Further more, we should add checking at the package generating
time, if the package *with recipe name* was empty and not created,
trigger a warn and according the warn, we could fix the issue recipes.

We already have that checking at the package generating time,
but it a note, not warn. I suggest we should use warn instead.
