Created attachment 526436 [details] kernel 4.16.0 Makefile In recent 4.15.x and in 4.16.0 gentoo-source I have experienced an error during compilation, reported by bash, looks like some missing argument before the && token. I am running 4.15.9-gentoo which compiled well, I transferred .config to the new kernel sources, make oldconfig and then: jp linux-4.16.0-gentoo # make CHK include/config/kernel.release CHK

The error happens also when compiling 4.16.2.
Can you attach your .config ?
Created attachment 527926 [details] .config Here .config is attached.
The same behavior with 4.16.3
The same problem with 4.16.5
The same in 4.16.6
I have finally found the problem - it was an exported environment variable "export host=jp". After "unset host" the compilation runs without problems. So for me the problems is solved, but maybe the make process of the kernel should somehow sanitize the environment, not to get confused by something the user defines.
