nine times out of ten the configure script is the culprit when
cross-compiling fails.  Assuming all dependencies have successfully
cross-compiled and are in the correct location.  ;-)

The above line is wrong, '-I/usr/include' shouldn't be there.

To better resolve this, start with a virgin motion source tree, in a new
terminal (no extra vars set), and send us the exact configure command
you used (including any variables that you need to set, eg, CC, CFLAGS,
etc) as well as the output of it.

Also, which cross-compiler are you using?  Yes, it's
armv7tl-hardfloat-linux-gnueabi-gcc, but who packaged it?  Is there a
pointer to their build methodology?  Lastly, have you already
cross-compiled ffmpeg to the proper location?
