To allow extended use, we need to enable CONFIG_FIT_SIGNATURE
otherwise we won't have the support.

See:

# MXSImage needs LibSSL
ifneq ($(CONFIG_MX23)$(CONFIG_MX28)$(CONFIG_ARMADA_38X)$(CONFIG_ARMADA_39X)$(CONFIG_FIT_SIGNATURE),)
HOSTLOADLIBES_mkimage += \
        $(shell pkg-config --libs libssl libcrypto 2> /dev/null ||
echo "-lssl -lcrypto")

If you do that, we can likely rely on this and avoid some extra tools
packages (for example on meta-freescale).
