D’oh!

We should fix it, notably because libc automatically falls back to the
normalized codeset (that is, if you choose “en_US.uTF--8”, it eventually
tries to read data for “en_US.utf8”.)  I wonder why the
‘install-locales’ rule doesn’t to it.

The “normalized codeset” is described in the libc manual (info "(libc)
Using gettextized software") and (info "(libc) Locale Names").

Anyway, I’ve posted patches to refactor things a bit and to create those
symlinks in ‘glibc-locales’:

Let me know what you think.

Thanks!
