Just to update everyone, I spoke to Shantanu offline and we experimented 
with using a debian chroot where we can satisfy the dependencies required
to port our packages to arm v6.

We finally agreed however to create a debian build server for the 
purpose of porting everything in one go and then returning to the chroot 
approach - as we would
have a complete hamara arm v6 repo by that point.
