Wrong, most (if not all) of the MMU targets use the MMU.

Wrong. It supports anything that linux supports + more.

Because the uClinux-dist is more about building firmware, and it
doesn't matter whether you are ELF/flat/fdpic or whatever, if you are
building firmware the uClinux-dist is designed to do it in an easily
reproducible way suitable for use in products.
uClinux is just "linux" with some extras, nothing is taken out, so you
are just using a regular linux kernel :-)
