No, being MMU-less has nothing to do with whether you can do shared
libraries or not, you just aren't able to do COW.

At the moment there are two options for shared support, there's a shared
flat format (grep the kernel for CONFIG_BINFMT_SHARED_FLAT), and then
there's support for FDPIC ELF (currently only implemented for FR-V).
Look at fs/Kconfig.binfmt in a recent 2.6 kernel to get a better idea of
your options.

Barring that, you may also want to post your inquiry to uClinux-dev, as
it's a more appropriate forum for these questions.
