I have not actually bisected this or tried to otherwise figure out exactly what is wrong, but the kunit code ends up being really annoying for my build testing. In particular, if I do make repeatedly - ie with no other changes in between - the kunit code ends up re-building itself for no apparent reason. Which then causes a re-link and makes it all really slow. Maybe I'm barking up the wrong tree, but just do make allmodconfig and then do two plain "make"s in succession (feel free to add "-jXYZ" to make it go much faster ;). The second build - that shouldn't have to re-build anything - still does this: CALL scripts/checksyscalls.sh DESCEND objtool CHK kernel/kheaders_data.tar.xz CC lib/kunit/hooks.o AR lib/built-in.a CC lib/kunit/hooks.o AR lib/kunit/lib.a AR built-in.a AR vmlinux.a LD vmlinux.o ... and it all takes much longer than an empty kernel build _should_ take.
