Nrf9160dk Build failed for asset tracker application.

Same problem here - same build errors when building nrf/applications/asset_tracker on tag v0.4.0.

I'm using command-line build on my Windows PC using cmake and ninja to build the apps.  Zephyr samples build, as does nrf/samples/nrf9160/at_client.

I'll track down the issue and update this thread.

Problem compiling zephyr/misc/generated/configs.c.

In file included from C:/iot/nordic/ncs/zephyr/include/toolchain.h:21:0,
from zephyr/misc/generated/configs.c:7:
zephyr/misc/generated/configs.c: In function '_ConfigAbsSyms':

These generated configuration symbols in configs.c have no value, causing the compilation error.

line 23: GEN_ABSOLUTE_SYM(CONFIG_FLIP_INPUT, );

line 30: GEN_ABSOLUTE_SYM(CONFIG_TEMP_SIM_BUTTON, );
