Commit [1] "package/uboot-tools: fix host FIT signature support"
slightly changed the logic in which the file
$(@D)/include/generated/autoconf.h is created.

When there is no Kconfig sub-option selected, the file is no longer
created and the build fails with error:

    include/linux/kconfig.h:4:10: fatal error: generated/autoconf.h: No such file or directory

The issue can be reproduced with the with the simple commands:

    cat >.config <<EOF
    BR2_aarch64=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_PACKAGE_HOST_UBOOT_TOOLS=y
    EOF
    make olddefconfig
    make host-uboot-tools

This commit fixes the issue by simply adding a touch of the file
at the beginning to make sure it will always exist.
