Well,
This is exactly what i386-uclibc is all about...
I had a hard time building a toolchain inside debian for i386-uclibc, so
I gave up and now I'm using gentoo-embedded as a seed to this new arch.
Enerv is working on a move from gentoo stage1 to 3 again because they
choosed to make the architecture i386-gentoo-linux-uclibc instead of
i386-pc-linux-uclibc. But besides that problem, I made dpkg understands
the i386-uclibc architecture, in a not-so-good way... but it seems to
work (only with dpkg 1.13).
BTW, this is what I have now inside my gentoo-embedded chroot...

I needed to patch dpkg in some ways (including configure) to support
sub-arches. It's working, but I really would like to see a better
solution.
What I made was... If it's a linux-uclibc os, sticks to $cpu-uclibc...
I'm now working on discovering the best order to build the 87 needed
source packages to get a base+buildessential set for debootstrap.
Follows the patches I made on dpkg...
