Hi Yamada-san,

Since commit:

80463f1b7bf9 kbuild: add --include-dir flag only for out-of-tree build

I can no longer run the bindeb-pkg rule. For example:

$ make O=wii ARCH=powerpc wii_defconfig
$ make -j8 O=wii ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- bindeb-pkg
...
  WRAP    arch/powerpc/boot/dtbImage.wii
INFO: Uncompressed kernel (size 0x89aa8c) overlaps the address of the
wrapper(0x600000)
INFO: Fixing the link_address of wrapper to (0x900000)
rm arch/powerpc/boot/wii.dtb
 fakeroot -u debian/rules binary
make KERNELRELEASE=4.19.0-rc3-wii+ ARCH=powerpc KBUILD_SRC= intdeb-pkg
/bin/bash ../scripts/package/builddeb

Would you be able to provide a patch to fix this ?

Thanks much,
