configs: add raspberrypi3 64bits defconfig
This configuration builds a 64bit image for RaspberryPi 3. The size of the ext4 filesystem has to be extended to fit the large amount (~60MB) of kernel modules enabled in the defconfig. [Peter: drop gcc version selection / glibc, explain ext4 size requirement] Signed-off-by: Gaël PORTAY <gael.portay@savoirfairelinux.com> Tested-by: Ricardo Martincoski <ricardo.martincoski@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
