...just a little question: why --disable-video-direct and _NOT_ --disable-video-directfb ?

It sounds an wrong compiler issue to me. Wrong compiler version?
Wrong INCLUDE path? No mention about wrong LIKER path, as soon as linker
step are away from here now... But check these out too...

Usually I am cross-compiling in two steps:

1) Compile on PC using the _SAME_ compiler as toolchain has
  (i.e.: if cross tools has arm-linux-gcc-3.4.1, then use gcc-3.4.1 in host)
  and if it works, then switch to pass 2
2) Cross compile in the way you did above.

Good luck!
Cheers,
