Readme

Refactor Use RPI_MODEL and SET_ARCH to define all board relevant settings, crosscompilers, architectures etc... - SET_ARCH=32 is default and used for all boards in 32bit mode - SET_ARCH=64 and RPI_MODEL=3 or 3P activate 64bit mode! - no need to set CROSS_COMPILE, KERNEL_IMAGE, RELEASE_ARCH, KERNEL_DEFCONFIG, KERNEL_ARCH, QEMU_BINARY - build kernel is now a default. i kicked out old kernel v3 and jessie support! they're too old. set buster as default - autodetect if program is running on 3142 => assume it is apt-cacher-ng and set APT_PROXY - next pull includes sakaki kernel for RPI3 and RPi3B+ => see https://github.com/sakaki-/bcmrpi3-kernel-bis

always include locales - so many errors connected to locals in the past and a check that always hits => just make it default - UBoot 64bit wanted bc to compile
