I got to the bottom of this, I was switching between native and cross 
compiling but only running 'autoreconf -i' so it was detecting libtool 
was already present from previous native runs and not replacing it with 
our 'cross' version of libtool. I feel like there should be a binary 
compatibility check in there to auto overwrite if they don't match, but 
hey ho.

Always use autoreconf -if to force update of all the required autotools 
scripts in future.

Cheers,
Jack.
