try adding packagegroup-cross-canadian-${TRANSLATED_TARGET_ARCH} in
TOOLCHAIN_HOST_TASK_append which will add cross toolchain to your sdk which
includes cross gdb as well. There is no nativesdk-gdb afaik unless if
someone says otherwise. see ./recipes-core/packagegroups/
packagegroup-cross-canadian.bb for details.
