The exception in analyze_outcomes.py follows previous commit in which
a test in test_suite_pkparse was set with the ECP_C guard for a different
parsing of the private key between the legacy and PSA implementations.
The wrong guard in test_suite_ecp.function instead was erroneously
added in a past commit and it was setting a non-existing symbol of
mbedTLS so those tests were basically never executed.
