[oe] getting back to < 2MB rootfs with mtd-utils

[Cliff Brake]

I have been experimenting with small images again trying to get a
uclibc initramfs image with mtd-utils around 1MB.  So far I've
learned:

- minimal-image is not all that minimal any more
- micro-image is better
- micro-base-image is slightly smaller (1.6MB vs 1.7MB) yet as it uses
mdev instead of udev
- micro distro builds eglibc and is about 6MB for micro-base-image
- micro-uclibc distro does not build for cm-x270

micro-base-image is currently 1.6MB for cpio.gz, which is much larger
than the 1MB uclibc images I built about a year ago, but that would be
acceptable.

However, adding mtd-utils to the image which I need for system update
functionality bloats it up to 4MB.

So I need to figure out why mtd-utils is pulling in so much stuff.
Also, it would be nice to remove opkg.  These are mostly just notes as
I work through this, but if anyone has good ideas, they are welcome
:-)
