I gave a whirl at building and looking closely at them. As it seems
the OE core patch is
not needed since for armv8 we want to keep it like x86 ( common )
I have therefore made changes to your patches and staged them here.

https://github.com/kraj/meta-raspberrypi/commits/kraj/master

Which should work without any change in OE-Core, secondly I have
further divided them
and also fixed 4.8 to compile arm64.

I think it will be better to rebase them to 4.8 and eventually 4.9 if
they are not too intrusive.
