Without the proper default tune in TUNE_FEATURES, certain variables
won't expand correctly. MACHINEOVERRIDES won't add cortexa72-cortexa53:
TUNE_CCARGS won't add -mtune=cortexa72.cortexa-53, generating the toolchain
incorrectly.
Adding missing 'cortexa72-cortexa53' to both
TUNE_FEATURES_tune-cortexa72-cortexa53 and
TUNE_FEATURES_tune-cortexa72-cortexa53-crypto
