I think that may be the problem. ( I'm completely new to this ).

Dynamic section at offset 0xce014 contains 22 entries:

I was concerned about the way I was doing this the other night.
I was successfully ( in appearance at least ) able to run a full stage4
crossdev on my local dev box: crossdev --t i686-pc-linux-uclibc .
THis completed successfully, we're talking linux-headers, gcc, uclibc,
etc. My '/etc/portage/catagories' has "cross-i686-pc-linux-uclibc". I was
able to then install/(bootstrap) uclibc w/ gcc and linux-headers onto my
'/mnt/gentoo' partition, basically like so:
ROOT="/mnt/gentoo" CHOST="cross-i686-pc-linux-uclibc" emerge cross-i686-pc-linux-uclibc/linux-headers
etc,etc.
The suspicion that I was doing something wrong, however, didn't occur until
I attempted to install some other necessary packages, such as bash:
ROOT="/mnt/gentoo" CHOST="cross-i686-pc-linux-uclibc" emerge bash
would cause:
"checking build system type... Invalid configuration `cross-i686-pc-linux-uclibc': machine `cross-i686-pc' not recognized
configure: error: /bin/sh ./support/config.sub cross-i686-pc-linux-uclibc failed"
So, trying a few different (basically random) things, I gave up and compiled it without
that CHOST env var - figuring that I would need to kind of recompile/'bootstrap' things
once I chroot'd into the new sandbox.
Here is ( what I believe to be ) a relevant portion of the bash config.log:

If you meant to cross compile, use `--host'.
