It works slightly different.

The final kernel config is generated by merging 
target/linux/generic/config-4.14 + target/linux/lantiq/config-4.14 + 
target/linux/lantiq/<subtarget>/config-4.14 .

Symbols common for all subtarget are moved (manually?) to 
target/linux/lantiq/config-4.14.

To really update the file you need to run make kernel_menuconfig 
CONFIG_TARGET=subtarget for each subtarget. Symbols added or removed for 
all subtargets can be dropped from or added to 
target/linux/lantiq/config-4.14.

One more comment inline.

I'm quite sure that removing this config symbol will cause a build error 
for all subtargets != xrx200, if you build with CONFIG_ALL_KMODS=y as 
the buildbot does.
