Add support for UcSlugC builds.

(1) the 'standard' settings in local.conf.template (from the nslu2-linux.org
master makefile) have been folded back into the three distro .conf files.
(2) openslug-image now builds for any NSLU2 distro
(3) ucslugc configuration added
(4) more comments in the openslug and ucslugc configuration files
