So with this, I then get:
Configuring for venice2 board...
make[2]: *** [arch/arm/dts/tegra124-venice2.dtb] Error 1
make[1]: *** [dts/dt.dtb] Error 2
make: *** [sub-make] Error 2

Device Tree Source is not correctly specified.
Please define 'CONFIG_DEFAULT_DEVICE_TREE'
or build with 'DEVICE_TREE=<device_tree>' argument

make[2]: *** [arch/arm/dts/tegra124-venice2.dtb] Error 1
make[1]: *** [dts/dt.dtb] Error 2
make: *** [sub-make] Error 2

--------------------- SUMMARY ----------------------------
Boards compiled: 1
Boards with errors: 1 ( venice2 )
----------------------------------------------------------

What's going on as the config file sets CONFIG_DEFAULT_DEVICE_TREE
