i just wanted to point to build-process where KBUILD_OUTPUT is used :)

thank you very much...i remember why (because the sudo) i passed the vars here i already exported ;)

i tried the KERNEL_DIR here (found somewhere but not checked in Makefile), but not the KBUILD_OUTPUT, don't ask me why...with passing KBUILD_OUTPUT there all works as expected.

sudo make ARCH=$ARCH INSTALL_MOD_PATH=$INSTALL_MOD_PATH KBUILD_OUTPUT=$KBUILD_OUTPUT modules_install

Thanks for pointing to this ;)
