Fix several issues regarding the support for Flat Image Trees (FIT).
- Add a patch to really allow turning FIT support on/off, which was not
possible due to bugs in the code and in the tools Makefile. This patch
has been sent upstream but not applied there, yet.
- Use independent options to control FIT support on host and target
packages.
- Subordinate FIT signature support to the activation of FIT support, in
the target package, not to mkimage installation.
- Add a dependence on the dtc utilities because mkimage needs it when
FIT is enabled; otherwise mkimage fails like this:
$ mkimage -f firmware.its firmware.im
sh: dtc: command not found
- Add BR2_PACKAGE_UBOOT_TOOLS_MKIMAGE_FIT_SIGNATURE_SUPPORT to the
Config.in.legacy file.

+Subject: [PATCH] Make FIT support really optional
+
+Due to some mistakes in the source code, it was not possible to really
+turn FIT support off. This commit fixes the problem by means of the
+following changes:
+
+- Enclose "bootm_host_load_image" and "bootm_host_load_images" between
+ checks for CONFIG_FIT_SIGNATURE, in common/bootm.c.
+
+- Enclose the declaration of "bootm_host_load_images" between checks for
+ CONFIG_FIT_SIGNATURE, in common/bootm.h.
+
+- Condition the compilation and linking of fit_common.o fit_image.o
+ image-host.o common/image-fit.o to CONFIG_FIT=y, in tools/Makefile.
