Thanks for the test, I checked GENERIC against GENERIC64 and the
bluetooth items are missing from the the 64 version and I think GENERIC
is only for building 32 bit versions. So, I have created a GENERIC64BT
adding in those missing bt items and started a build, but RPi3 is slow
to build tools and kernel, and it will take many hours to compile
everything. If I get a kernel, I will try to boot it.
