UBSAN_BOUNDS and UBSAN_TRAP depend on UBSAN config option. merge_config.sh script generates following warnings if parent config doesn't have UBSAN config already enabled and UBSAN_BOUNDS/UBSAN_TRAP config options don't get added to the parent config.
Value requested for CONFIG_UBSAN_BOUNDS not in final .config Requested value: CONFIG_UBSAN_BOUNDS=y Actual value:
Value requested for CONFIG_UBSAN_TRAP not in final .config Requested value: CONFIG_UBSAN_TRAP=y Actual value:
Fix this by including UBSAN config.
