On my system (fedora 14 x86_64), the valid locales are stored in:
and part of libX11-common

together with /usr/share/X11/locale/locale.alias which defines aliases (like the lowercase/uppercase with without "-" above). 

I had an impression that these things used to be glibc-common or glibc-locale, but it seems that they have moved.
