The problem is that the flags _are_ used in order to build the kernel -
make finally complains about unknown arguments - that's what it
complains about - I realize I haven't included the concrete output of
the make call (cut lots of output at the end):

make -j 8 HOSTCC=gcc  -isystem/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/recipe-sysroot-native/usr/include -O2 -pipe -L/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/recipe-sysroot-native/usr/lib -L/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/recipe-sysroot-native/lib -Wl,-rpath-link,/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/recipe-sysroot-native/usr/lib -Wl,-rpath-link,/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/recipe-sysroot-native/lib -Wl,-rpath,/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/recipe-sysroot-native/usr/lib -Wl,-rpath,/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/recipe-sysroot-native/lib -Wl,-O1 -Wl,--allow-shlib-undefined -Wl,--dynamic-linker=/home/david/yocto/kraemer-ng/poky/build/tmp/sysroots-uninative/x86_64-linux/lib/ld-linux-x86-64.so.2 HOSTCPP=gcc  -E zImage CC=i586-poky-linux-gcc  -fuse-ld=bfd -fdebug-prefix-map=/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0=/usr/src/debug/linux-vortex86/4.14.65-r0 -fdebug-prefix-map=/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/recipe-sysroot= -fdebug-prefix-map=/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/recipe-sysroot-native=  -fdebug-prefix-map=/home/david/yocto/kraemer-ng/poky/build/tmp/work-shared/vortex86/kernel-source=/usr/src/kernel -ffile-prefix-map=/home/david/yocto/kraemer-ng/poky/build/tmp/work/vortex86-poky-linux/linux-vortex86/4.14.65-r0/git=/kernel-source/  LD=i586-poky-linux-ld.bfd   

make: invalid option -- 'y'
make: invalid option -- '/'
make: invalid option -- '/'
make: invalid option -- '/'
make: invalid option -- 'E'

How come all these options (-isystem etc. etc.) are passed to the make
call to build the kernel? This is wrong - these are not make options,
instead, it should contain ARCH=a CROSS_COMPILE=b etc. but not the
arguments used - the ones really necessary are not present at all.

Can anyone tell me what is wrong with my recipe? Is this not the
recommended way to go? If not, how should I include a kernel for a
machine that linux-yocto does not initially support?

Thanks!

Best Regards
