This gives me:
make[2]: *** No rule to make target '../include/generated/autoconf.h', needed by 'arch/powerpc/boot/autoconf.h'. Stop.
The ../ is $(srctree).
Seems autoconf.h is in objtree:
~/linux$ make O=build prepare
...
~/linux$ find . -name autoconf.h
./drivers/staging/rtl8723bs/include/autoconf.h
./tools/testing/radix-tree/generated/autoconf.h
./build/include/generated/autoconf.h
So I'll fix that up.
cheers
