Summary: Linker error when compiling minimal ScummVM

Initial Comment:
While looking at a BS2 bug a while ago, I tried to
compile a minimal version with only the BS2 engine
included. At the time I had trouble building it, but
since someone else helped me diagnose the bug, I didn't
look any further into it.

Now I decided to try again, using the most recent SVN
snapshot. This is the configure command I used:

./configure --disable-scumm --disable-simon
--disable-sky --disable-sword1 --disable-queen
--disable-saga --disable-gob --disable-kyra
--disable-mt32emu --disable-scalers
--disable-hq-scalers --disable-mad --disable-flac
--disable-fluidsynth --disable-nasm

Which for me meant I ended up with the following features:

Engines:
    Broken Sword 2 (w/ mpeg2 cutscenes)

Backend... sdl
Looking for sdl-config... /usr/bin/sdl-config

Compiling seemed to go well, all the way to the final
linking, which produced the following output, which I'm
not sure quite how to interpret:
