Sorry no docs but knowing your space constraints 

cat /etc/portage/root_install_mask 

Or just export what you want to mask via the INSTALL_MASK= env var.

emerge -b busybox uclibc
emerge -B baselayout-lite
ROOT=/dev/shm/ROOT \
 emerge -KO uclibc busybox baselayout-lite

# let busybox set up it's symlinks.
mount --bind /proc /dev/shm/ROOT/proc
chroot /dev/shm/ROOT/ /bin/sh --login
busybox --install -s
umount /dev/shm/ROOT/proc

# these three pkgs should be your base for everything else you need

good luck and dont forget to setup your inittab/fstab/init scripts.
