You can build all the sys packages with a CHOST of i386-pc-linux-gnu and merge them
to some temporary place.
Then chroot there and recompile and remerge all packages. Eighter do this a few times
or follow the dependencies
starting by glibc to be sure you have no statically linked in i486 assembler code in
there. Then you can build the
other stuff you need and you should have a i386 based system.
Do you still use i386 ? My oldest is an i486SX/25 with a 200MB HD running as a
firewall here under gentoo.
The i486 version is definetly slower that the i686 version we had before using i386
won't make things better.
If there really is a need for a i386 version I can build one.

Currently about 200MB with lots of package-docs, and the development tools, but if
you unmerge
all sys-devel packages beside the c++-libs and spython remove /usr/doc and /usr/src
and all the static libs in /lib and /usr/lib you only need about 130MB and still have
a runable system. Other optimizations could be turning of building
of localdata-stuff in glibc removing unneccesary zoneinfo and terminfo entrys...

Hmm, maybe we should introduce a new USE flag to trigger build of packages with only
the really neccesary stuff.
