Gilles Peskine 7d112ae04c Check in test_suite_psa_crypto_not_supported.generated.data
This test data file is automatically generated. We could do that as
part of the build, since the only requirement is Python and we have a
requirement on Python to build tests anyway (to generate the .c file
from the .function file). However, committing the generating file into
the repository has less impact on build scripts, and will be necessary
for some of the files generated by generate_psa_tests.py (at least the
storage format stability tests, for which stability is guaranteed by
the fact that the generated file doesn't change). To keep things
simple, for now, let's commit all the files generated by
generate_psa_tests.py into the repository.

This script checks that all generated file are up-to-date. If some aren't, by
default the scripts reports it and exits in error; with the -u option, it just
updates them instead.
-u Update the files rather than return an error for out-of-date files.
