I did not review the entire patch, but those last two lines look
incorrect. The purpose of the
BR2_PACKAGE_UBOOT_TOOLS_MKIMAGE_FIT_SIGNATURE_SUPPORT option was to
enable support for FIT signature in the *target* variant of
uboot-tools. Hence, I don't see why you are selecting host-dtc and FIT
support in the host variant of uboot-tools.

It would be good to mention the upstream status of this patch. At least
so that I remember instead of asking you again and again if it has been
sent upstream :-)

I'll do a full review later on. Thanks!
