In real world, the need to expicitly mention kernel is really rare.
It's nice to have all these variations of kernels and c libraries in
one distribution, however, emdebian haven't got so far as to have
linux+glibc properly (with one exception), so let us leave hurd and
openbsd support for now.

Excuse me, it doesn't result in anything at the moment. Correct me if
I'm wrong, but the only implementation of uclibc targets as of today
is slind.

If your architecture says uclinux-i386, it means one and only thing
that your libc is uclibc and your kernel is uclinux (and not linux).
Otherwise if it says uclibc-i386, your kernel is linux and libc is
uclibc. No problem here.

P.S. Once again, let's move architecture-related discussions from this thread.
I am free of all prejudices. I hate every one equally.
