For now you need a locale supporting environment to build the 
locales data. Manuel is working on removing this dependancy (Feb/Mar). I 
have (re)generated the data myself in a glibc env (removing stuff not 
used by me, I want to go only with UTF locales, 8859-1(5) is last resort, 
but no other), and then used it in the build process instead of the 
pregenerated data. If you need it for other archs, gentoo's devs have 
access to the different archs, ask them to generate the data and create 
the tarballs (uClibc-locale-arch-date.tgz) and you'll copy these over the 
original one (see uclibc.spec).
