configs: add raspberrypi3 64bits defconfig

Browse Source 
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]
