make_generated_files.py --check doesn't return a failure status #244
Description
Currently on Mbed TLS development (at caaa93884c9aefb1bb416a64ea26c1a0eef29140), all.sh check_generated_files complains:
Generated file tests/suites/test_suite_ecp.generated.data not identical to the reference one tests/suites/test_suite_ecp.generated.data.ref.
Generated file tests/suites/test_suite_psa_crypto_op_fail.generated.data not identical to the reference one tests/suites/test_suite_psa_crypto_op_fail.generated.data.ref.
Generated file tests/suites/test_suite_psa_crypto_storage_format.current.data not identical to the reference one tests/suites/test_suite_psa_crypto_storage_format.current.data.ref.
Generated file tests/suites/test_suite_psa_crypto_storage_format.v0.data not identical to the reference one tests/suites/test_suite_psa_crypto_storage_format.v0.data.ref.
That's from running ./framework/scripts/make_generated_files.py --check inside tf-psa-crypto after running make -f scripts/legacy.make generated_files. But we never noticed this complaint because make_generated_files.py --check always returns 0.
