We have a general guide that might be useful here:

http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html#building-a-tiny-system

(Whether you actually need to use poky-tiny itself is a separate question,
but it does explain some of the techniques used to generate it.)

Ultimately, removing things comes down to figuring out how they got there in
the first place. The Toaster Web UI, or the graphs produced by buildhistory for
the image and bitbake -g may be useful in that process - but note that not
everything can be removed easily.

Cheers,
Paul
