I noticed something similar while trying to get locale.aliases to work
(see https://bugzilla.yoctoproject.org/show_bug.cgi?id=11815). I don't
know why the .utf8 suffixes to do not appear, but it might be related
(perhaps some configuration in glibc is incorrect?). Based on a little
bit of testing I did, I think that the utf8 locale might be present as
you can do setlocale(LC_ALL, "de_DE.utf8") in C and it should work (you
might want to check this yourself). Perhaps the locale program just
isn't showing it?

I think you would need to set $LANG to actually change the language,
i.e.

$ LANG="de_DE.UTF8" locale
