The ones that don't will run if I build them will run using the download of the corresponding kernel image from the repository - these were built from the same source under 4.5.1. I thought it would be worth trying with another version.

well either way you have work to do. I think making kernel work with
4.6+ is forward looking and will be beneficial in future too. It would
be nice to know
whats the gcc 4.5 dependency, which version of kernel are we talking about ?
