I fully agree with you that cross-compiling is the better approach, but 
for the sake of completness let me mention that it is not really 
necessary to port the tools to bionic. Statically linked binaries built 
on Ubuntu work fine in recovery. You can push them using adb and then 
run them from adb shell. Again cross compiling using for example 
arm-eabi-gcc is the best way to build them.

These commands should work in recovery for extending the UT system image:

   truncate -s 3G /data/system.img
   resize2fs /data/system.img
